     TECHNICAL FIELD 
     This application relates generally to scales used for weighing food product in supermarkets, groceries and other stores, and, more particularly, to a scale including advantageous interface configurations and functionality. 
     BACKGROUND 
     In typical commercial food product scale applications the scale is used to weigh food products and determines prices for the food products, and an associated printer prints a label for application to the food product. An operator enters a product number, such as a PLU (price look-up) number, for the product being weighed and the scale accesses its database, or accesses a remote database, for pricing information on the product. The total price for the item is then determined based upon its weight. 
     Operators and consumers have grown to expect more dynamic functionality and operations from devices. It would be desirable to provide a scale facilitating such functionality and operations. 
     SUMMARY 
     In one aspect, a scale includes a weigh station for receiving items to be weighed, an operator interface configured to display information associated with scale operations and a controller operably coupled to the operator interface to effect display of information thereon. The controller is configured such that multiple primary interface screen views are made available for operator use, wherein each of the primary interface screen views includes: (i) a plurality of fixed features that are common among all the primary interface screen views, each fixed feature residing in a common location in each of the primary interface screen views; and (ii) other features that are not common with the other primary interface screen views. 
     In one example, one of the plurality of fixed features is a group of adjacent screen view icons, each screen view icon associated with one of the plurality of primary interface screen views in a one-to-one correspondence. The controller is configured such that each screen view icon is displayed in either a present state or background state, and the state of each screen view icon is automatically adjusted upon transition from one primary interface screen view to another primary interface screen view such that only the screen view icon associated with the primary interface screen view that is being displayed is displayed in the present state. 
     In another example, the controller is configured such that one of the plurality of primary interface screen views is designated as a home interface screen view, and one of the plurality of fixed features is a home view icon that when triggered causes the home interface screen view to be displayed. In such example, the controller may be configured such that designation of the home interface screen view can be changed as between a first of the primary interface screen views and a second of the primary interface screen views. In such example, the controller may also be configured such that three or more primary interface screen views are provided, and at least one of the primary interface screen views cannot be designated as the home interface screen view.

     DETAILED DESCRIPTION 
     Referring to  FIGS. 1 and 2 , an exemplary scale configuration is shown. The scale  10  includes a weighing station  12 , which in some embodiments may be formed by a weighing platter  13  that can be removed (e.g., for cleaning) from atop the scale housing  14 , and having an associated mechanism such as a load cell located internal of the scale housing  14 , for producing weight indicative signals when items are placed on the weighing station. An operator interface side  16  of the scale includes an operator interface  18  configured to display information associated with scale operations. By way of example, the operator interface  18  may be formed by a touch-screen display. A customer interface side  20  of the scale includes a customer interface  22 , which in certain embodiments may be formed by any suitable display screen technology. It is contemplated that the customer interface  22  need not include touch-screen capabilities, but it is recognized that in certain embodiments touch-screen capability could be incorporated into the customer interface as well. A side portion  24  of the scale housing includes a label exit slot  26  and incorporates a label printer therein along with a label supply station. The label printer may use any suitable printing technology. A removable side panel  28  is provided to access the label supply station for replacement of the labels and to access the label printer and the label path for maintenance etc. Alternatively, member  28  may take the form of a removable cassette. 
     Referring to  FIG. 3 , an exemplary scale system  30  is shown (e.g., located in a store perishables department such as a deli department, meat and fish department or baked goods department) having a counter  32  with a customer side  34  and a service person side  36 . The scale system includes a scale  10  located atop the counter  32  and adapted for weighing and pricing food items. In the illustrated embodiment a single scale  10  is shown, but many departments will include multiple scales. Likewise, while a single counter is shown, many departments will include multiple counters arranged adjacent each other to effectively form one continuous counter. In an alternative embodiment, the scale may be a hanging scale located above the counter  32 . As shown, in certain embodiments the scale counter may be located in front of a meat slicing station  38  that includes one or more food product slicers  40 . Although shown in the context of a department including a customer facing side or region, it is recognized that in certain applications the scales will not be used in an environment where the interface  22  faces a customer or customer location (e.g., a back-room or other location where items are not being weighed directly in front of the customer, such as a bakery department). In addition, some scales may also include a self service functionality, that enables store customers to weigh and price items. Moreover, in certain implementations the scale or scale system may be an integrated part of a package wrapper (e.g., of the type used to wrap meat products in the back room of the supermarket). In such an implementation the load cell may be located along a package feed in path of the machine. 
     In one example of a typical item pricing operation an operator enters an item identifier (e.g., a price look-up number or PLU) via the operator interface, and the scale retrieves price and other product information associated with the PLU and displays product information. The operator places the item (e.g., just sliced by the operator or selected from a container within the deli counter or elsewhere, or in the case of self service selected from a food display or stand) on the weighing station, and the scale prices the item based upon weight and displays that price on both the operator interface and the customer interface. When the desired amount of the product is achieved, the operator presses a print button on the operator interface and the scale prints a label with item details (e.g., item name, item weight, item price) that is then applied to a package in which the item is placed before the package is handed to a customer. In another example, which is more common in a bakery department, the scale  10  may price an item by an item count entered by the operator (e.g., in the case of an item with a PLU that indicates a price based upon item count). 
     As used herein, the term “operator” refers broadly to any person interacting with the user interface of the scale. Thus, the term “operator” includes, for example, each of (i) regular store employees that may have access to basic scale functions/operations, (ii) supervisor type store employees that may have access to basic scale functions/operations and more advanced scale functions/operations, (iii) service personnel that may have access to special service-based scale functions/operations and (iv) store customers (e.g., where a scale is set-up for operation in a self service mode). When the term “operator” is used in the claims, and unless otherwise dictated by other express limitations of the claim, the term should be construed broadly enough to encompass one or more of the foregoing exemplary operator types. However, when the term “operator” is used in the claims, and unless otherwise dictated by other express limitations of the claim, the term should not be construed as requiring applicability to more than one of the exemplary operator types. 
     Referring now to  FIG. 4 , a high level schematic depiction of the scale  10  is shown, including a controller  50  interconnected with each of the operator interface  18 , customer interface  22 , weighing station  12 , label printer  52  and a communications interface  54 , and having associated memory  56 . The controller  50  may, for example, be any suitable processor-based controller, including one or more processors, such as a dual-core processor, with associated hardware, software and firmware to achieve desired functionality. As used herein, the term “controller” is intended to broadly encompass the collection of circuits, processors, software, firmware and/or other components that carry out the various operating and processing functions of the scale and its component parts as described herein. The operator interface  18  may include both a display device  58  and touch-screen panel  60  as shown. The weight station platter  13  is operatively connected to a load cell  62 , which produces weight indicative signals. The communication interface  54  may be any suitable type (e.g., as a hardware link, such as a standard network connector, or may be formed by a wireless device such as an RF or infrared transceiver), and it is recognized that multiple communications interfaces may be provided. Memory  56  may, by way of example, take the form of one or more of non-volatile flash memory and/or random access memory, or disk on module or micro-SD. As explained above, the controller  50  is operable to establish a price for a weighed item based in part upon a weight indicative signal produced for that item. In this regard, the scale controller may include its own database of product price information (e.g., price per pound) that it retrieves when the operator inputs the PLU number or other product identifier of an item being weighed. Alternatively, in certain embodiments, the controller may utilize the communication interface  54  to access a remote computer system having the database of product price information on other product information. Although not shown in  FIG. 4 , in certain embodiments the scale may also include an RF operator identification system in which operators utilize RF identification units (e.g., in the form of wrist-band type units, or other structures) that are worn proximate to the hands of the operator. Such a system is described in U.S. Pat. No. 7,041,915. 
     Enhanced functionality and operations of food product scales are desired. In order to provide such enhancements in a straightforward and streamlined manner, such a scale  10  may be provided with an operator interface that utilizes multiple interface screen views. Specifically, and referring to  FIG. 5 , multiple primary interface screen views  70 A,  70 B and  70 C are shown in side by side relation, with the currently displayed interface screen view represented within dashed line region  72 . Although three primary interface screen views are primarily described herein, it is recognized that embodiments having only two primary interface screen views and embodiments having more than three primary interface screen views are also possible. As used herein the terminology “primary interface screen view” is intended to encompass a first level screen view, that is, a screen view that can be presented for display without first clicking or passing through another screen view. As will be described in further detail below, each primary interface screen view is at the ready for display (e.g., meaning that it stands ready to be displayed, such as in RAM), even though only one of the views is being displayed at any given time. In the arrangement of  FIG. 5 , from the perspective of the operator, the interface screen views  70 A,  70 B and  70 C appear to be arranged side-by-side horizontally, so that operator selection of a different interface screen view is achieved by some interaction that designates another screen view that is either to the left or to the right of the currently displayed screen view. By way of example, such selection could be achieved by a left or right swiping operation along the operator interface, by selection of a left or right screen view indicator arrow or by selection of a screen view icon that is one of multiple screen view icons displayed horizontally side-by-side on each screen view. In an alternative arrangement depicted in  FIG. 6 , from the perspective of the operator, the interface screen views  70 A,  70 B and  70 C appear to be arranged one atop another vertically, so that operator selection of a different interface screen view is achieved by some interaction that designates another screen view that is either above or below the currently displayed screen view. By way of example, such selection could be achieved by an up or down swiping operation along the operator interface, by selection of a an up or down screen view indicator arrow or by selection of a screen view icon that is one of multiple screen view icons displayed in a vertically stacked manner on each screen view. 
     In other embodiments, from the perspective of the operator, the interface screen views could appear to be arranged both side-by-side horizontally and one atop another vertically. For example, with reference to  FIG. 5 , in order to provide five screen views, a fourth screen view could be perceived as being above screen view  70 A and a fifth screen view could be perceived as being below screen view  70 A. Thus, from screen view  70 A an operator could swipe in any one of four directions to access another screen view, but from either of screen views  70 B and  70 C, as well as the proposed fourth and fifth screen views, the only screen view accessible by swiping would be the center screen view  70 A. 
     Referring now to  FIGS. 7 and 8 , an exemplary primary interface screen view  70 A is shown. The interface screen view  70 A includes each of a metrology bar  80 , a PLU description line  82 , a product tracking information line  84 , a menu button/icon  86 , a home button/icon  88 , a dynamic content area  90 , and a keypad area  92 . The illustrated metrology bar  80  for a by weight item includes each of a WEIGHT field  80 A, a TARE field  80 B, a UNIT PRICE field  80 C and a TOTAL PRICE field  80 D. However, where the product is a by count, by fluid ounce or fixed weight item the metrology bar fields may vary The PLU line  82  includes each of a PLU # field  82 A, a product name/description field  82 B and a SELL BY field  82 C. The product tracking information line  84  includes a COOL (country of origin label) field  84 A, a BEST BEFORE field  84 B and PACKED ON field  84 C. The illustrated dynamic content area  90  includes multiple selectable buttons, but could include other content as will be described in more detail below. The keypad area  92  includes multiple selectable numeric buttons, as well as print  92 A, return  92 B and backspace  92 C buttons. The operator may use the keypad to enter a PLU number, which causes product price and other information to be retrieved and loaded into the various fields as shown by way of example in  FIG. 8 . 
     Notably, in the top section of the screen view  70 A, a further set of display features is provided. These display features include a capacity string  94 , a ZERO indicator  96 , a screen view location indicator  98 , an alert indicator section  100 , a scale operating mode indicator  102  and a date and time indicator  104 . The capacity string  94  shows the scale capacity, with current capacity range is shown within a trapezoid. The ZERO indicator  96  is an icon that appears when no weight is on the scale and the scale is at zero load. The screen view location indicator  98  is an icon or group of adjacent icons that shows which of the three screen views is being displayed. In this case, three side-by-side rectangular icons, with the rectangle shown in solid reflecting an active state of that icon and depicting the screen view that is currently being displayed, and with the rectangles not shown in solid reflecting a background state of that icon showing the other screen views that exist, but that are not currently being displayed. Thus, each one of the adjacent screen view icons or frames is associated with one of the of primary interface screen views in a one-to-one correspondence, and only one of the screen view icons is displayed as active at any given time in accordance with the primary interface screen view being displayed at the given time. In certain implementations, the controller  50  may be configured such that the screen view icons are selectable, and selection of a given one of the screen view icons will cause the primary interface screen view associated with the given screen view icon to be displayed. The alert section provides four different alert icons, representing four different alerts, namely a Generic Alert icon, a Printer Alert icon, a Planogram Alert icon and a Network Connectivity alert icon. 
     The Generic Alert icon  100 A will flash (e.g., red) when one or more alert messages occurs (e.g., a product recall message is available, or other alert not addressed by a more specific alert icon). Touching the icon will cause the message to be displayed. The icon will remain white (e.g., not flashing) when there are no active generic alert messages. 
     The Printer Alert icon  100 B will flash (e.g., red) when there is a printer issue such as the label cassette is open or the printer is out of labels. Touching the icon will cause the message to be displayed. The icon will remain white (e.g., not flashing) when no message exists. 
     The Planogram icon  100 C will flash (e.g. red) when a planogram image is available. Touching the icon will cause the planogram image to be displayed. The icon will remain white (e.g., not flashing) after the planogram image has been viewed. 
     The Network Connectivity icon  100 D will either display a hard wired icon or will show bar strength for a wireless connection. If connectivity is lost, the background of the scale application will be red and the icon will be red and flashing. 
     Notably, the capacity string  94  and the metrology bar  80  may be connected in the control software design. All required active screen information from Weights &amp; Measures is within these two lines. For operator ease, the PLU # field  82 A and item description field  82 B are side by side. All PLU information is viewed in the top half of the screen view, helping the operator concentrate in a smaller area. In  FIG. 7 , the PLU # field is outlined in and offset color (e.g., blue rather than white), because in this image the cursor is in the PLU # field designating it as the active field, helping the operator know where the scale is and if it&#39;s expecting a command. The product tracking line or row  84  contains information that is commonly used in Deli/Meat/Seafood departments, but that is generally not necessary for a bakery or a floral department. These fields  84 A,  84 B and  84 C can be hidden, as will be described in more detail below, thus making the overall screen layout more effective for departments not needing this information. 
     Referring now to  FIGS. 9-11 , exemplary primary interface screen views  70 B are shown in which a major portion of the view is a dynamic content area  110  that can be set to display multiple different sets of content. For example, in  FIG. 9  the dynamic content area displays customized flashkeys, which may be varied/selected as described further below, for different item types that can be selected to retrieve further information regarding such item types, such as flashkeys for specific PLUs. In  FIG. 10  the dynamic content area displays item PLU #s and names for a plurality of items (e.g., as flashkeys), which may be varied/selected as described further below. Selection of a PLU key from the view in  FIG. 10  may function to load the corresponding PLU data into the PLU fields  82  of primary interface screen view  70 A, even though that primary interface screen view is not being viewed. Likewise, in certain implementations, such selection of a PLU key from the view of  FIG. 10  may also cause an automatic transition to screen view  70 A. In  FIG. 11  the dynamic content area displays a web browser that the operator can use to retrieve/view information. 
     Referring now to  FIG. 12 , an exemplary interface screen view  70 C is shown. Notably, unlike the screen views  70 A and  70 B, the displayed field in screen view  70 C are fixed and cannot be modified. Screen view  70 C includes a discount pricing line  120  (e.g., UPC, DISCOUNT UNIT PRICE, DISCOUNT TOTAL PRICE and SAVINGS fields), a product life display region  122  (e.g. SHELF LIFE and PRODUCT LIFE), label information display regions  124  (e.g., LABEL STOCK, PRIMARY LABEL ID and PRIMARY GRAPHIC ID display fields) and  126  (e.g., ADDITIONAL LABEL ID and ADDITIONAL GRAPHIC ID display fields), additional product information display region  128  (e.g., displaying EXPANDED TEXT, RECIPE, COOKING INSTRUCTIONS and/or ALLERGENS information, each with an associated print icon that can be used by the operator to print the information) and nutrition facts panel display region  130  (e.g., having an associated print icon  132  that can be used to print a nutrition facts label). The data for the fields on screen view  70 C is automatically retrieved and loaded based upon the PLU # entered by the operator on screen view  70 A, so that the data is ready and available for the operator when the operator shifts to screen view  70 C. 
     Notably, also present in each of the screen views  70 B and  70 C, are the capacity string  94 , ZERO indicator  96  (not shown in screen view  70 C because the screen view presumes an item on the weighing scale), the screen view location indicator  98 , the alert indicator section  100 , the scale operating mode indicator  102  and the date and time indicator  104 . Moreover, screen views  70 B and  70 C also include the menu button/icon  86  and the home button/icon  88 . Thus, as between the multiple screen views  70 A,  70 B and  70 C there is a degree of similarity based upon certain fixed features that are common between the screen views, and a degree of difference based upon other features that are not common between the views. Thus, the scale provides a unique and desirable interface arrangement. 
     In particular, the controller  50  is operably coupled to the operator interface  18  to affect display of information thereon, with the controller configured such that multiple primary interface screen views (e.g.,  70 A,  70 B and  70 C) are made available for operator use. Each of the primary interface screen views includes: (i) a plurality of fixed features (e.g., features  86 ,  88 ,  94 ,  96 ,  98   100 ,  102  and/or  104 ), that are common among all the primary interface screen views, where each fixed feature resides in a common location in each of the primary interface screen views, and (ii) other features that are not common with the other primary interface screen views. The most prominent of the fixed features include the home button/icon  88  and menu button/icon  86 . Notably, the controller  50  may be configured such that one of the screen views  70 A,  70 B and  70 C is designated as a home interface screen view. Triggering the home button/icon  88  from either of the non-home interface screen views causes a transition back to display of the designated home interface screen view. The controller  50  may be configured such that designation of the home interface screen view can be changed as between at least two of the primary interface screen views as reflected in  FIGS. 13-16 . Likewise, the controller may be configured such that the scale automatically boots to the designated home screen upon start-up. 
       FIG. 13  shows an initial pop-up window  140  that appears upon operator triggering of the menu button/icon  86 , which includes the following items menu icon  142 , search icon  144 , language toggle icon  146 , help icon  148  and shutdown icon  150 , with a default selection of the menu icon  142  (e.g., as reflected by the surrounding frame of the icon  142  being offset in a different color (e.g., blue) than the frame colors (e.g., white of the other icons). This default selection results in the simultaneous display of an operator pages button  152 , a supervisor pages button  154  and a service pages button  156 , with the operator pages button  152  selected as default. This default button selection results in the display of various operator task buttons  158 . In the exemplary embodiment, the home screen view selection is made by way of the supervisor pages button  154 , the selection of which causes the window view to change as reflected in  FIG. 14  to present a number of supervisor task buttons  160 , including a scale operations button  160 A designated as Normal Operations. Selection of button  160 A causes the screen view to display the data shown in  FIG. 15 , which includes a task selection bar  162  with buttons for Product  162 A, Scale Access  162 B, System  162 C, Flashkeys  162 D, Network  162 E, Features  162 F and Accumulate  162 G, where the Product button  162 A is the default selection. By selection of the System button  162 C the display transitions to that shown in  FIG. 16 , which presents numerous system features that can be modified, including a Home panel feature  164  with a drop down menu  166  that allows selection of which screen view (here referred to as a “panel”) is the designated home screen view that is associated with the home button/icon  88 . In  FIG. 16  the center screen view  70 A is designated as the home screen view, but an alternate screen view can be selected from the drop down menu. Notably, where more than two primary interface screen views are provided, the controller may be configured such that less than all of those screen views can be designated as the home screen view. For example, in the above described embodiment including with primary interface screen views  70 A,  70 B and  70 C, only screen views  70 A and  70 B may be selectable as the home interface screen view, while screen view  70 C cannot be designates as the home interface screen view. The purpose of including this limit is where one or more of the primary interface screen views is limited in its usefulness to the operator (e.g., as in the described embodiment where interface screen view  70 C is only useful if a PLU number has been entered in order to retrieve and load data into the fields of screen view  70 C). 
     Referring again to the fixed features common to interface screen views as described above, a method of achieving this operator interface arrangement involves: identifying a set of critical interface features (i.e., to be the fixed features, such any of features  86 ,  88 ,  94 ,  96 ,  98   100 ,  102  and/or  104 , or others that may be suitable), incorporating the critical features into at least a first interface screen view (e.g., view  70 A) and a second interface screen view (e.g., view  70 B) that are presentable to operators via the operator interface in a manner that enables operators to switch between the first interface screen view and the second interface screen view, identifying a first set of primary features for the first interface screen view, the first set of primary features focused on a primary function of the first interface screen view (e.g., the metrology bar  80  of interface screen view  70 A for use in weighing), incorporating the first set of primary features into the first interface screen view, identifying a second set of primary features for the second interface screen view, the second set of primary features focused on a primary function of the second interface screen view (e.g., the dynamic content area  110  of screen view  70 B for use by operators to obtain information) and incorporating the second set of primary features into the second interface screen view. 
     As mentioned above, various techniques may be used to transition between the multiple primary interface screen views. Where the operator interface  18  is formed by a touch-sensitive display, the controller  50  may configured to enable transition from one primary interface screen view to another primary interface screen view via a swiping operation along the display in one of a horizontal direction or a vertical direction. In one example of such an arrangement, and referring again to  FIG. 4 , the touch-sensitive display includes a viewing area reflected by the rectangular area of the display device or screen  58 , and a touch-sensitive member  60  with a primary portion  60 A that overlies the viewing area  58  and a secondary portion  60 B (e.g., shown with stippling in  FIG. 4  and framing the viewing area  58 ) that is external of the viewing area. In this arrangement, swiping operations can be achieved using the secondary portion  60 B of the touch-sensitive member  60 . 
       FIG. 17  shows an exploded partial view of one example of the operator interface including both the touch-screen panel  60  and the display screen  58 , as well as housing components  170 ,  172  and circuitry panel/component  174 . Primary portion  60 A and secondary portion  60 B of the touch-sensitive panel are both shown. The touch-sensitive member may be formed by a plate (e.g., glass or plastic) with a perimeter portion that is opaque so as to frame an interior portion that is transparent. Here, the perimeter portion defines the secondary portion  60 B and the interior portion defines the primary portion  60 A. The interior portion of the glass plate aligns with the display screen  58  positioned behind the glass plate. A printed layer is applied to a back side of the glass plate to achieve opaqueness of the perimeter portion  60 B. In addition to the opaqueness, the printing may be used to apply fixed visible indicia on the back side of the glass plate to indicate swipe functionality outside the perimeter of the interface viewing area. As best seen in  FIG. 18 , where the visible indicia takes the form of left and right swipe arrows  176  and  178 . However, the indicia could take other forms (e.g., such as verbal indicia indicating Swipe Here) or a swiping bar that extends the full width of the viewing area. In the example of  FIG. 18 , the primary portion  60 A of the touch sensitive plate is shown as blank and aligns with the viewing area of the display. The remaining portions of the touch sensitive plate are shown with cross-hatch marking and represent the portions of the plate that include printing on the back side. The remaining portions include the secondary portion  60 B immediately surrounding the primary portion  60 A and that is also touch sensitive, and a third portion  60 C which frames the secondary portion  60 B and that is not touch-sensitive. 
     In the illustrated example, the secondary portion of the touch-sensitive panel frames the entire viewing area, thereby enabling swiping operations in any of those regions immediately adjacent the viewing area. Thus, all such regions could include the swiping indicia mentioned above. However, it is recognized that the secondary portion need not necessarily frame the entire viewing area (e.g., it could be located only above and below or only to the left and right sides of the viewing area). Providing the swiping area external of the viewing area is particularly useful where, as is the case in the illustrated example, the viewing area is largely covered with selectable fields, making it difficult to swipe within the viewing area without inadvertently selecting a field. 
     Referring again to  FIGS. 7-12 , and as alluded to above, each primary interface screen view is at the ready. When a PLU number is entered, for example in primary interface screen view  70 A, data is automatically loaded into interface screen view  70 C (e.g., in RAM) so that if an operator swipes to transition to screen view  70 C, that screen view  70 C will contain the loaded information immediately upon viewing. Moreover, when an operator swipes to transition away from, for example, a populated primary interface screen view  70 A (e.g., per the view shown in  FIG. 8 ) to one of the other views  70 B or  70 C, and then subsequently swipes to transition back to the primary interface screen view  70 A, the primary screen view  70 A returns as a populated view (i.e., the PLU based data that was previously loaded remains in the screen view  70 A for viewing). 
     Thus, in such an embodiment, the controller is configured such that item information retrieved and displayed on the item weigh primary interface screen remains populated when an operator transitions from the item weigh primary interface screen view (e.g., in this case screen view  70 A) to another primary interface screen view (e.g., in this case screen view  70 B or  70 C) and back again. Moreover, screen view  70 C represents a supplementary product information primary interface screen view that includes additional product-related display fields (e.g.,  120 ,  122 ,  128  and  130 ) and when identity data regarding an item to be weighed is entered by the operator at the item weigh primary interface screen view (e.g., PLU entered at screen view  70 A) the controller is configured so that it automatically retrieves and loads the additional product-related display fields with data even though the supplementary product information primary interface screen view is not being displayed on the operator interface. Notably, these features of implementations using multiple primary interface screen views (i.e., the automatic retrieve and load feature, and screen view data remaining populated even after a transition away from the screen view) enhance overall operator interaction with, and ease of use of the scale. 
     As used herein, the terminology “remains populated” when referring to the information and/or data of a screen view is intended to broadly encompass the situation in which the information and/or data is still presented on the screen view when the operator returns to the screen view. Thus, in one example, the information and/or data remains populated as a result of the information and/or data never being removed from the fields of the screen view (e.g., even when the screen view is not being displayed or when a pop-up window is being displayed over the screen view). In another example, the information and/or data remains populated as result of being temporarily removed from the fields of the screen view and stored (e.g., upon transition away from the screen view or upon over display of a pop-up window on the screen view) until the information and/or data is later automatically loaded into the fields of the screen view (e.g., as triggered by a call to return to display of the screen view or as triggered by a call to close the pop-up window that is displayed over the screen view). 
     In addition, and referring specifically to  FIGS. 13 and 14 , in certain embodiments, the item weigh primary interface screen view (e.g.,  70 A) includes a selectable menu icon (e.g.,  86 ). As noted above, selection of the menu icon triggers display of an menu interface pop-up window (e.g.,  140 ) over the item weigh primary interface screen view, which causes the fields of the item weigh primary interface screen view to no longer be selectable. An operator can access many types of supplemental information through the pop-up window  140 , as well as perform other functions. When the operator is finished with the information look-up, the pop-up window  140  can be closed (e.g., as by hitting the home button or hitting the screen anywhere outside of the pop-up window  140 ), leaving the item weigh primary interface screen view  70 A presented on the screen with its fields again in a selectable state. Thus, in such an implementation, the controller is configured such that item information retrieved and displayed on the item weigh primary interface screen view remains populated when an operator temporarily accesses and then closes the menu interface window. Again, this feature facilitates enhanced operation of the scale, enabling an operator to, for example, look-up information in the middle of a weighing process without having to restart the weighing process (e.g., reenter the PLU#) once the information look-up is completed. 
     Thus, an advantageous method of facilitating user access to information during performance of a weighing operation using a scale is provided. The method involves the scale receiving identity data regarding an item to be weighed (e.g., based upon operator enters a PLU# via the displayed keypad or selects a displayed PLU flashkey). The scale responsively displays on an item weigh primary interface screen view retrieved item information for the given item (e.g., PLU #, unit price, product name etc.) in at least one product-related display field on the item weigh primary interface screen view. The interface subsequently transitions (e.g., responsive to an operator swiping operation or menu button selection) from display of the item weigh primary interface screen view to one of a different primary interface screen view (e.g.,  70 B or  70 C) or a menu interface window displayed over the item weigh primary interface screen view (e.g., pop-up window  140 ). The interface subsequently again transitions (e.g., responsive to another swipe or to pop-up window closure) back to display of the item weigh primary interface screen view, with the retrieved item information for the given item continuing to be displayed in the product-related display field. The operator is thereafter able to complete the weighing operation that had been initiated. 
     In order to facilitate ease of operator use, one or more of the screen views may be adjustable according to, for example, store preference or operator preference. In this regard, and referring to the item weigh primary interface screen views shown in  FIGS. 7 and 8 , the scale controller may be configured to enable straightforward and simple screen view format adjustment. By way of example, in  FIGS. 7 and 8  the keypad area  92  is located in the lower right quadrant or corner of the screen view. As shown in  FIG. 13 , selection of the menu button/icon generates a pop-up window  140  initially displaying operator pages, but including a supervisor pages button  154  that can be selected to access different functions per  FIG. 14 . This window displays only the most used supervisor functions, but additional functions can be accessed by selecting the all functions button/icon  180  in the bottom right corner of the pop-up window, which selection generates a larger pop-up window display  182  as shown in  FIG. 19 . Among the various options available is a Move Layout button/icon  184 . 
     Selection of the Move Layout button/icon  184  causes the display of the layout adjustment screen view shown in  FIG. 20 . As shown, two groups of buttons, keys and/or fields  186 ,  188  are shown with a defined outline (e.g., a surrounding yellow box) or other set-off indicator to alert the supervisor that these two parts of the screen view can be moved. The supervisor can select either grouping and simply drag the grouping in order to move its position on the screen view. 
     In particular, by selecting the keypad grouping  186  and dragging it to the left side of the screen view, the position of the keypad grouping  186  will snap to a new position at the left side of the screen view and at the same time the product tracking information line  84 , menu  86  and home  88  buttons and the dynamic content area  90  will automatically shift to the right. By selecting grouping  188 , which includes the metrology bar  80 , capacity string  94 , zero indicator  96 , screen view location indicator  98 , alert indicator section  100 , mode selection  102  and date  104 , and dragging the grouping  188  toward the bottom of the screen view, the grouping will snap to a new position along the bottom of the screen view, but with the relative vertical positioning of the metrology bar  80  and the other parts of the grouping reversed (i.e., the metrology bar above the capacity string  94 , zero indicator  96 , screen view location indicator  98 , alert indicator section  100 , mode selection  102  and date  104 ). At the same time the other parts of the screen view will be automatically shifted upwards slightly. The result of both layout adjustments is reflected in the screen view shown in  FIG. 21 . When the supervisor is done, in order to exit the layout adjustment screen, the supervisor simply triggers the home button. Triggering of the home button saves any changes made. Generally, tapping off screen will return close any pop-up or other adjustment window without saving changes that have been made. 
     Thus, the scale controller is configured to enable adjustment of the item weigh primary interface screen view by dragging and dropping at least one grouping of displayed fields and/or icons in order to shift the grouping from one location on the item weigh primary interface screen view to another location on the item weigh primary interface screen view. The controller is also configured to effect automated adjustment of locations of other parts of the item weigh primary interface screen view to accommodate the shift of the grouping. 
     As mentioned above, a snap to location feature is used in connection with the drag and drop of the groupings  186 ,  188 , meaning that the groupings cannot be moved to any desired location on the screen view. Instead, the scale controller is configured such that the locations at which the groupings can be moved are predefined locations. In the case of the grouping  188 , in the illustrated embodiment the locations are either a top of screen view location and or a bottom of screen view location. In the case of the grouping  186 , the locations are either a right side of screen view location or a left side of screen view location. As reflected in  FIG. 21 , the shifting of the grouping  188  from the top of screen view location to the bottom of screen view location will also automatically result in a slight movement of the keypad grouping  186 . However, each grouping is movable independently of the other. 
     With respect to the keypad grouping  186 , adjustment as between left and right side of screen view locations, it is noted that such adjustment is particularly useful to accommodate both left-handed and right-handed operators. That is, left-handed operators may typically prefer the keypad grouping  186  to be on the left side of the screen view and right-handed operators may typically prefer the keypad grouping  188  to be on the right side of screen view. 
     As noted above, in the described embodiment the controller is configured to enable adjustment of the position of each grouping via a drag and drop operation by setting each group as an active field group enabling the drag and drop. However, other variations are possible, such as display of a toggle button for each grouping (e.g., a left/right toggle for grouping  186  and a top/bottom toggle for grouping  188 ). Moreover, while the adjustment function is described as a supervising operator function, it is recognized that in some embodiments it could also be implemented as a non-supervisor type operator function. When all layout adjustment operations are complete, pressing the home button  88  will exit the adjustment screen view of  FIG. 20 . 
     As noted above, certain areas of the screen view may be dynamic content areas. In particular, and referring to the item weigh interface screen view as shown in  FIG. 22 , dynamic content area  90  includes a set of flash keys, but the content of such area can be adjusted. Moreover, the keypad area  92  and the product tracking information line  84  can also be considered dynamic in that such areas can either be eliminated or content display modified. By way of example, and referring to  FIG. 19 , where the supervisor selects the Change Fields button/icon  190 , the scale controller effects display of the adjustment interface screen view  200  of  FIG. 23 . The dynamic content area  90  will display whatever content is currently set for the area, which in this case is a web browser interface. Fields that that have a square box  202  in the upper right hand corner can be hidden by simply pressing inside the box where an “x” appears. In this case, the Sell By, COOL, Best Before and Packed On fields can all be hidden. Notably, the fields can each be individually and selectively hidden on a case by case basis (i.e., the fields are not an all or nothing). If each of the COOL, Best Before, and Packed On fields are hidden, the scale controller auto adjusts the dynamic content area  90  to be larger so as to fill the space previously taken up by the now hidden fields, as shown in  FIG. 24 . Thus, the scale controller is configured to effect automatic adjustment of a display size of one dynamic content area to fill the space previously taken by another dynamic content area that becomes hidden or removed from the screen view. If only one or two of the three fields is hidden, then the dynamic content area  90  remains at the smaller size. Thus, in the illustrated example, all of the display fields immediately above dynamic content area  90  must be hidden or turned off in order for the scale controller to effect adjustment of the display size of dynamic content area  90 . 
     Returning to  FIG. 23 , areas that have customizable options have the toggle arrows  204  in the upper right hand corner. Pressing an arrow will move the supervisor through whatever the available display options for that specific area (e.g., web browser, flashkeys or best seller keys for dynamic content area). By way of example, in  FIG. 24  the dynamic content area  90  displays a web browser page and a keypad is displayed alongside the web browser page, whereas in  FIG. 25  the dynamic content area  90  displays function flash keys and a set of item best seller flash keys is displayed alongside the function flash keys. When content adjustments are completed in the adjustment screen view  200  of  FIG. 23 , pressing the home button  88  will exit the adjustment screen view and save the adjustments. 
     In an arrangement such as that shown in  FIG. 25  with best seller flash keys displayed instead of the keypad, when an operator activates a field (e.g., such the PLU field), the scale controller automatically displays the keypad instead of the best seller flash keys to allow an operator to enter a PLU number. When used in prepack mode, this same area  292  may display, for example, run totals for the prepack operation. 
     With respect to flash keys, a variety of different options exist, and the scale controller enables operator adjustment of the specific flash keys that are displayed. In this regard, referring to  FIG. 13 , after pressing the menu button  86  the operator can select the Flashkey Editor button/icon  220 , in which case the screen view  222  shown in  FIG. 26  will be presented. Screen view  222  presents existing flashkeys and available spaces at  224 , which are associated with the dynamic content area  90  (the number of flashkeys and the grid layout is configured in the Supervisor Mode), and presents available flashkey options at  226 . Numerous flashkey options may exist, such as any of the following: (1) Select Product/Specific PLU—This function will load the information for the PLU assigned to this flashkey; (2) Load Softkey Group—Takes the operator to another set of flashkeys; (3) Load Category—Takes the operator to another set of flashkeys containing subcategories and items that have been assigned to the specified category; (4) Print Label—A label will print if a product is entered and weighed; (5) Platter Tare—Allows the operator to adjust the platter tare; (6) Percent Off Discount—allows the operator to apply Percent Off Discounts; (7) Reset Price—Allows the operator to reset the price of a product to its original value; (8) Home Panel—Takes the operator to the Configured Home Panel; (9) Search—Takes the operator to Search Screen; (10) Operator Login—This will login the operator; (11) Show Expanded Text—Displays the expanded text field on the operator screen; (12) Show Expanded Text 2—Displays the expanded text 2 field on the operator screen; (13) Show Recipe—Displays the recipe field on the operator screen; (14) Show Cooking Instructions—Displays the cooking instructions field on the operator screen; (15) Show Suggestive Sell—Displays the suggestive selling field on the operator screen; (16) Show Allergens—Displays the Allergens field on the operator screen; (17) Label Data—Takes the operator to the Label Data Screen; (18) Product &amp; Shelf Life—Takes the operator to the Product and Shelf Life Screen; (19) Printer Settings—Takes the operator to the Printer Settings Window; (20) Total Types—Takes the operator to the Total Types Window; (21) Expiration History—Takes the operator to the Expiration Label Window; (22) COOL—Takes the operator to the Create COOL Window; (23) Void Transaction—Takes the operator to the Void Transaction Window; (24) Preset Tares—Enters a preset tare value into the tare field; (25) Browse Web—Takes the operator to the default internet web address, if available; (26) Operator logout—This will logout the current operator and set the scale for the next operator to login; (27) Load Specials—Takes the operator to another set of flashkeys sorted by specials; (28) Store Applications—Enter Applications URL, ability to include CGI parameters; (29) Production Planning—PP URL, ability to include CGI parameters; (30) Print New Shelf Life Label—Prints a new shelf life label for the active PLU; (31) Print Multiple Labels—Allows scale to print multiple labels for active PLU; (32) Change Language—Enables screen to toggle from primary language to secondary language; (33) Print Existing Shelf Life Label—Prints an existing shelf life label for the active PLU; (34) Load Best Sellers—shows the best selling products based upon historical data; and (35) Show Accumulate Items—displays the list of accumulated items on operator screen. 
     The operator can select from the pre-determined flashkey list  226 , touch the desired flashkey and drag it to an open key space  224  on the grid, as reflected in  FIG. 27  where the Existing Shelf Life Label flashkey  230  has been added. The key color background can then be set using the drop down menu  232  under the Background Color designation  234  as shown in  FIG. 28 . Once the desired flashkeys have been set, the operator presses the home button  88  and the adjusted flashkey grid will be applied to the dynamic content area  90  of the item weigh primary interface screen view. 
     Referring again to  FIG. 14 , a supervising operator can also make certain flashkey adjustment by selecting the Flashkeys button/icon  240 . Because such an adjustment is considered a common supervisor task, the button/icon  240  is made available on the opening pop-up window  140 , without requiring the supervisor to press the All Functions button/icon  180 . Triggering the Flashkeys button/icon results in display of the flashkey set-up screen view  242  shown in  FIG. 29 . The Feature drop down menu  244  enables selection one of multiple groupings of flashkeys to be configured (e.g., the flashkeys for the primary interface screen view  70 B, the flashkeys for the dynamic content area  90  of the primary interface screen view  70 A, the flashkeys associated with the tare field of the primary interface screen view  70 A (i.e., flashkeys that show up in the dynamic content area when the Tare field  80 B is selected) or the flashkeys that fill the keypad area of the primary interface screen view  70 A when the keypad is hidden). Depending upon which grouping is selected, the displayed grid  246  will auto-adjust to the amount of space available for that grouping. Adjustment of the number of rows or columns of flashkeys is achieved by selection of the appropriate row or column plus buttons  248 ,  250  and minus buttons  252 ,  254 . If there is a desire that a specific flashkey take up more space horizontally or vertically, selection of the appropriate row span or column span plus buttons  256 ,  258  or minus buttons  260 ,  262 . For example, to make a specific flashkey horizontally take the space of two cells, the row span plus button  256  would be triggered. Once the grid is set up as desired, the supervisor selects the Create New Cell button  264 , which causes the flashkey list to be displayed. Desired flashkeys can then be selected for drag and drop to the desired grid location. 
     Referring again to  FIG. 13 , a convenient process for changing the display language of the scale is described. In particular, pressing the menu button/icon  86  brings up the pop-window  140 , which includes the language toggle button/icon  146 . Selection of button/icon  146  causes the scale to immediately toggle to a default second language and return to the designate home screen. By way of example, the scale can be set up to toggle between English/Spanish or English/French. This process only requires the operator only to press two buttons to change the language. By contrast, in current scales, the operator must drill down 3-5 layers to change this setting. Notably, only the user interface portion of the screen view shifts languages, the data that has been uploaded to the scale and that may be displayed in certain fields or locations remains in whatever language it was uploaded. Also, in one implementation, the unit of measure and the language are not connected. For example, when changing to French, the measurement does not auto change to metric/kilograms. 
     A search button/icon  144  is also included in the pop-up window  140  and can be used to carry out an item/PLU search. The length of time to complete a search is drastically reduced in the present scale (e.g., in prior scales from 60-90 seconds, while in the present scale within 2-5 seconds). An operator can search using letters, numbers or a combination of both, whereas in prior art scales they could only search on alpha or numeric, but not a combination. In the present scale the operator can enter as many letters/numbers as necessary. Upon selecting the search button/icon  144 , the search screen view  270  shown in  FIG. 30  is displayed. Notably, such search screen view is populated with a QWERTY keyboard to facilitate user typing of the search request. As the operator begins to type, a search list  272  is populated and continues to evolve as more characters are added, as suggested in  FIGS. 31 and 32 . As suggested in  FIG. 33 , the operator can select the desired item (e.g., item  274 ) when it appears in the list, which automatically loads PLU data into the item weigh primary interface screen view  70 A and returns the display to such view as per  FIG. 34 . 
     As noted above, a touch-screen display may be used in connection with the scale, and it may be of the color-type to enhance the operator experience and functionality. Scale purchasers in the grocery and supermarket industry focus on ease of use, reliability and durability. As is the case with any touch-screen display, the life span of the display is limited. However, certain features may be implemented by the scale controller so as to extend the display life or, in other words, reduce the number of maintenance and/or warranty claims. By way of example, the scale controller may be configured to effect a normal brightness setting during operator interaction with the touch-sensitive display. After a set time period without interaction, the scale controller implements a dimmed brightness setting for the touch-sensitive display. The dimmed brightness setting effectively enhances the overall working life of the display. In order to achieve this desirable result without adversely impacting scale function, during the dimmed brightness setting, one or more selectable icons or fields on the touch-sensitive display remain live and ready for operator selection. As used herein an icon or field remaining “live” is intended to mean that the icon or field can be immediately triggered by contact with the screen in the vicinity of the icon or field. That is to say, unlike known screen dimming functions which require two touches for user interaction (i.e., one touch to “wake” the screen function and another touch to then select an icon or field on the screen), the scale implemented as described above enables immediate operator activity by a single touch, making the scale more straightforward for operator use. 
     In one implementation, during the dimmed brightness setting and upon operator selection of the selectable icon or field, the selection of the selectable icon or field is automatically captured and a transition to the normal brightness setting is automatically effected. Moreover, the controller may also be configured such that, during the dimmed brightness setting, and upon detection of item placement on the weighing station of the scale (e.g., as determined by an output change of a load cell associated with the weighing station), a transition to the normal brightness setting is automatically effected. 
     Multiple stages of dimmed brightness may be implemented by the scale controller. For example, a first dimmed brightness setting (e.g., 60% of normal) may be initiated after a first set time period without scale interaction (e.g., 2 minutes). A second dimmed brightness setting (e.g., 40% of normal or other value less bright than the first setting) may be implemented after a second set time period without any scale interaction (e.g., 4 minutes or other time period longer than the first time period). In another example, the scale controller may be configured to effect a multi-tier dimming operation that includes transition to a dimmed brightness setting after a set time period and shut down of the display after a further time period, where upon shutdown of the display no selectable icons are active. 
     Notably, the scale may enable adjustment, via the operator interface, of one or more of the normal brightness setting, the dimmed brightness setting or the set time periods. In particular, and referring again to  FIG. 19 , in the supervisor menu the supervising operator selects the Setup utility button  300 , which produces the adjustment screen view  302  shown in  FIG. 35 . The brightness of both the customer display and the operator display can be adjusted by selecting the appropriate button  304  or  306 , and then using the up down arrows  308 ,  310  to define the percent of max brightness. These adjustments set the brightness level for normal operation, but not the amount of dimming. In one example, the dimming level may be predefined to trigger off of the normal brightness setting. For example, if the normal brightness is set to 90% of maximum brightness, and the predefined dimming level is 60% of normal, then the predefined dimming level will be 54% of the maximum brightness. In another example, the dimming level may be predefined to trigger off of the max brightness, regardless of the normal setting. For example, the predefined dimming level may be 60% of max, regardless of where the normal brightness setting is established. In an alternative embodiment, the dimming level could also be adjusted by the supervising operator in a similar manner. Notably, a lower limit on the normal brightness adjustment may be set in order to assure that the interface can be viewed sufficiently to allow interaction and control of the scale (i.e., so that the operator does not lose the ability to interact with the scale through the touch-screen display). 
     Referring now to  FIG. 14 , by selecting the Display Options button/icon  312 , the supervising operator will be presented with the adjustment screen view  314  shown in  FIG. 36 . By selecting the Operator Display option  316 , the supervising operator can then enter the number of minutes of non-use of the scale (e.g., minutes without a weight output and/or minutes without a touch-screen interaction) that will cause the dimming operation to be implemented. 
     Thus, the scale is configured to enable a unique method of operation that involves utilizing a first brightness (e.g., a normal brightness) setting for operation of the touch-sensitive display (e.g., during normal operator interaction with the scale). Thereafter, an automatic transition to utilization of a second brightness setting for operation of the touch-sensitive display is made, where the second brightness setting is lower than the first brightness setting (e.g., for the purpose of improving operating life of the touch-sensitive display). During utilization of the second brightness setting, the scale controller continues to monitor a touch-sensitive surface of the touch-sensitive display for operator selection of one or more displayed icons or fields and, upon operator selection of a given displayed icon or field, the selection is captured. The step of automatically transitioning to utilization of the second brightness setting may be triggered by monitoring one or more scale functions or, more appropriately, the inactivity of such functions. For example, a lack of operator interaction with the touch-sensitive display for a specified time period may trigger dimming and/or a lack of item weighing by the weighing station for a specified time period may trigger the dimming. 
     Regardless, as mentioned above the icons and fields of the operator interface display remain live, and upon operator selection of the given displayed icon or field, the scale controller may cause an automatic transition back to the first brightness setting for operation of the touch-sensitive display. Thus, the display “wakes-up” while simultaneously capturing the operator screen selection. Likewise, during utilization of the second brightness setting, and upon detection of item placement on the weighing station (e.g., as indicated by load cell output), the scale controller may cause an automatic transition back to the first brightness setting for operation of the touch-sensitive display. 
     In terms of the dimming operation, in one embodiment the customer facing display is not dimmed when the operator display is dimmed. This is particularly useful when the customer facing display is being used to communicate information to customers even when the scale is not in use, which will be described in more detail below. 
     In order to facilitate marketing operations via scales in the supermarket, it is possible for videos to be displayed on the customer facing interface or display  22 . In one embodiment, multiple different videos may be stored in scale memory and played in sequence. However, because the customer facing interface must, at times be used for displaying weigh and price information, a controlled interruption and restart of the sequence is implemented. More specifically, the scale controller  50  may be configured such that upon operator initiation of an item weigh and price operation during display of a specific video, display of the specific video is stopped and item weigh and price information is displayed on the customer interface. By way of example, operator initiation of the item weigh and price operation may be triggered via an item being placed on the weighing station for weighing (e.g., as indicated by load cell output). 
     Upon completion of the item weigh and price operation, display of a different video is automatically initiated on the customer interface (i.e., without completing or restarting the specific video that was interrupted). By way of example, the different video may be the video that sequentially follows the specific video in the defined sequence, and completion of the item weigh and price operation is triggered via a label printing operation. In this manner, the scale is operated to avoid confusion that might be caused by starting a video midstream, and to assure that the same video is not continually restarted during time periods when the scale is being used heavily. 
     With respect to the sequence of videos played on the scale, in one embodiment the sequence may be established by a playlist that can be modified via the operator interface. In particular, and referring to  FIG. 37 , the adjustment interface screen view  314  is shown with the Customer Display option  318  triggered. From this screen the supervising operator can modify any one of (i) lag time, if any, between non-use of scale and beginning to display the videos, (ii) customer display language, (iii) the playlist being used, (iv) the Layout (which allows you to choose from among different background images for the customer display when in the metrology displaying mode) and (v) the volume associated with the video display. By selecting the arrow buttons/icon  320  the supervising operator can select an alternate playlist from a drop down menu. By selecting the Edit button/icon  322 , the supervisor can edit the identified playlist, which may be in the form of a text file. Thus, in one example, by editing the text file the supervising operator may modify one or both of the plurality of customer information videos or the defined sequence to be varied by modifying the playlist in the text file. 
     Depending upon the location of the scale within a store, the need for certain functions can vary widely. For example, a scale located in the back-room may not make use of the customer video play function (i.e., that function may be turned off). Likewise, the manner in which the scale is used may vary depending upon store type and location within the store. Different scale modes are provided for this reason. For some departments, changing the mode of the scale can happen many times a day. 
     There are primarily two distinct scale modes, namely Manual and Prepack. However, some scales may include an additional Self Service mode as well. In the Manual mode single transactions (e.g., each weigh, price and label print is a single operation that is not related to any preceding or following weigh and price operation). A majority of scale activity is typically carried out in the Manual mode. In the Prepack mode multiple transactions are carried out, and this mode is most often used in back of store meat rooms. In the Prepack mode the operator enters a PLU, places the product on the scale for weighing and when the weight becomes stable the scale auto prints a label. The operator can then place the next cut of meat under the same PLU on the scale and a label auto prints. In the Self Service modes, customers in the store are able to individually weigh and price items. 
     In the case of the present scale, the transition between Manual and Prepack modes, and in some cases the Self Service mode, is facilitated by the mode selection button/icon  102  that is presented on the primary interface screen view  70 A ( FIG. 7 ). Selection of this button/icon  102  produces the adjustment pop-up window  332  shown in  FIG. 38 . Window  332  includes selections  334  and  336  for Manual and Prepack, and  337  for Self Service, enabling the operator to make a very simple transition between modes. As shown, there are 3 types of Item Entry processes available as well, namely Normal, Accumulate Items and Production Entry. The Normal item entry type involves single transactions as described above. The Accumulate Items entry type is used when multiple PLU&#39;s are sold in one transaction (bakery, meal counters, etc.). In this entry type the operator enters all PLU&#39;s, and the scale prints one label and gives a total price. The Production Entry entry type allows the operator to print multiple labels of the same PLU (for example, the operator can print 15 labels for 6 count white cupcakes). The Accumulate Items and Production Entry options are available on in Manual mode. 
     By way of example, when the Accumulate Items entry type is selected, the primary interface screen view  70 A of  FIG. 39  is presented, with item entry field  340  presented in the dynamic content area  90 . The operator enters a PLU like normal using the keypad and presses enter  92 B. The entered information populates the item entry field  340  when the operator presses Add Item on the Accumulate Items portion of the screen. The PLU entry process is repeated until all items are entered. Advantageously, the present scale therefore provides the ability for the operator to view the accumulated item list on the main interface screen view. 
     As noted above with respect to  FIG. 8 , the item weigh and price interface screen view  70 A may include a SELL BY field  82 C. The present scale may be configured to enable straightforward operator adjustment of that date. In particular, if the operator selects the SELL BY field  82 C, the scale automatically modifies the screen view  70 A to present the date adjustment window  350  in the dynamic content area  90  as shown in  FIG. 40 . The operator can then edit the date by selecting the actual day on the calendar or by entering the number of days using the keypad. By way of example, as seen in  FIG. 41 , the date has been adjusted from 12 days to nine days. Once the modification is set (e.g., by pressing the enter button/icon  92 B in this case), the scale controller immediately reverts back to the normal operating screen view  70 A with the modified Sell By date information populated as per  FIG. 41 . Thus, the present scale enables the operator to modify the sell by date information on the fly, during the weighing and pricing process, and without having to restart the weighing and pricing process. 
     Referring again to  FIG. 8 , as noted above the set of fixed features includes the icons in the alert indicator section  100 . The Generic Alert icon  100 A will flash (e.g., red) when one or more alert messages occurs (e.g., a product recall message is available, or other alert not addressed by a more specific alert icon). Touching the icon will cause the message to be displayed. The icon will remain white (e.g., not flashing) when there are no active generic alert messages. This can be a valuable tool if used for food recalls—essentially notifying departments immediately of recalls and giving retailers an additional form of communication to ensure this recall is acted on immediately. 
     The Printer Alert icon  100 B will flash (e.g., red) when there is a printer issue such as the label cassette is open or the printer is out of labels. Touching the icon will cause the message to be displayed per  FIG. 43  showing a pop-up message window  360  indicating that the label cassette is open and providing instruction to address the problem. If the operator hits the OK button  362 , the window  360  will close, but the icon  100 B will continued to flash (e.g., red) until the label cassette is closed. The icon  100 B will automatically revert to constant white and remain white (e.g., not flashing) when the label cassette is closed and the error no longer exists. 
     The Planogram icon  100 C will flash (e.g., red) when a new planogram image first becomes available. Touching the icon  100 C will cause a pop-up window  392  to be displayed per  FIG. 48 . This window shows one or more product area planogram options that are available for display, as per  394 . Selecting a planogram option  394  highlights or otherwise sets the planogram option  394  as the active option, and then selecting the View button  396  will cause a planogram image for that active option to be displayed per  FIG. 44  showing a large planogram image window  370 . This feature can enable store management (e.g., corporate headquarters of a chain) to send new planogram photos or diagrams directly to the scale, allowing for immediate communication to the operator and a providing close visual to enable reset of a counter display. Tapping outside the window  370  will close the window. The icon will revert to constant white (e.g., not flashing) after the image window  370  has been viewed, but the planogram image will still remain available for later viewing. In order to remove a specific planogram option, that option is selected in window  392  and then the Delete button  398  is selected. Tapping outside the window  392  will closed the window. 
     The Network Connectivity icon  100 D will either display a hard wired icon or will show bar strength for a wireless connection. When the scale loses network connection and goes off-line, the network connection icon will flash red and an initial system message will appear as per  FIG. 45  showing the system message window  380 . The operator must select the okay button  382  for this message to disappear, but the icon will remain active (flashing) until network connectivity is regained. Pressing the icon  100 D, either when active (flashing) or inactive (not flashing) causes a pop-up window to display network attributes will be displayed. By way of example,  FIG. 46  represents a pop-up window  390  when there is no network connection (e.g., the settings are all blank/have no data) and  FIG. 47  shows the pop-up window  390  when there is a network connection, with exemplary setting details/data shown. The information in the pop-up window  390  can be useful for troubleshooting purposes. 
     Thus, the alert indicator features of the scale provide a straightforward and readily accessible manner for operators to be made aware of and track alert messages. Even on the interface screen views that include multiple fields useful for performing item weigh and price operations, the plurality of alert icons  100 A- 100 D are also presented, each alert icon associated with a particular notification type. Each alert icon is selectively displayed in either an active state (e.g., flashing red) or an inactive state (e.g., constant white), depending upon whether the notification type associated with the alert icon does or does not exist. The alert icons  100 A- 100 D are displayed adjacent each other in a group to facilitate operator viewing, creating the alert indicator section  100  of the screen views. Notably, the alert indicator section  100  is positioned centrally along a width of the interface screen view and along a perimeter (e.g., upper in the illustrated embodiment) of the interface screen view to facilitate operator viewing. When a given one of the alert icons is being displayed in the active state, selection of the icon causes alert notification message information to be displayed (e.g., in a pop-up message window). 
     Notably, the planogram icon feature provides a desirable method of reorganizing a food product display area within a food retail sales establishment. The scale displays the planogram alert icon on the operator interface in an active state to notify the operator of an available planogram update. The operator selects the planogram alert icon to access an image of a desired layout of food product for the food product display area is then displayed. The operator then utilizes the image to adjust the food product display area to match the desired layout presented in the image. As per  FIG. 44 , the image may include both PLU number data and a product depiction for each food product in the desired layout. In certain embodiments, the scale may even permit the operator to print the image utilizing a printer associated with the scale. 
     As indicated above, multiple planogram options may be made available for display to the operator, enabling multiple product display areas to be adjusted. In such an operation, the operator selects the planogram access icon to cause display of multiple planogram options on the operator interface. The operator then selects (e.g., by touching the option and then hitting the View button) a first planogram option (which could be any of the planogram options displayed) to cause display of a first image of a desired layout of food product for a first food product display area. The operator then utilizes the first image to adjust the first food product display area to correspond to the desired layout presented in the first image. The operator then selects a second planogram option to cause display of a second image of a desired layout of food product for a second food product display area. The operator utilizing the second image to adjust the second food product display area to correspond to the desired layout presented in the second image. The process may be repeated for whatever number of planogram options are available. The operator may delete each planogram option after completion of any needed display area adjustments. 
     It is to be clearly understood that the above description is intended by way of illustration and example only, is not intended to be taken by way of limitation, and that other changes and modifications are possible.
