Notes About Operations

Power-on zero
 If the weight is unstable at power ON, the scale displays. Check anything
touches the weighing pan, or check if there is strong wind or vibration.
 The range for power-on zero is within ±50% (±10% for Legal for Trade models) of theweighing capacity (kg) at the adjusted zero point. If the scale is powered on with aload beyond this range, the scale displays. Remove the load from theweighing pan.
ZERO and TARE
 The
(as ZERO switch) and TARE switches work when the weight value isstable.
switch will zero the scale if the weight value is within ±2% of the Theweighing capacity (kg) at the power-on zero point. The ZERO◄ indicator turns on.
(ZERO operation) The TARE switch will tare the scale and subtract the weight to zero as a tare weight9

when the weight is a plus value. In this case the ZERO◄ and NET◄ indicators
turn on. (TARE operation) At the zero point, the net weight display shows the tareweight in negative, and the ZERO◄ and NET◄ indicators turn on.
(Note: In some countries or areas, the ZERO ◄ indicator will not turn on while
the scale is tared.) When the scale is tared, weighing range for net loads is reduced by the amount of
the tare weight.
 When the ZERO operation is performed in the net weight display, the tare operation
previously done is cleared and the NET◄ indicator turns off.
(Note: In some countries or areas, the ZERO operation will not clear the TARE
operation. Press the TARE switch after zeroing the scale with nothing
on the weighing pan.)
Auto power-off function
 If no switch is pressed and the stable indicator is displayed for a certain period oftime, the scale will automatically turn off. See the function setting
to set theelapsed time to turn off.
 Whenoris displayed (refer to "13.3. Error Codes"), the auto
power-off function is enabled.
LCD backlight The LCD backlight is controlled by the functionsand.
 If no switch is pressed and the weight display continues to be stable for a certain
period of time, the LCD backlight will automatically turn off. The elapsed time to turnoff is set by the function setting. The backlight always on or off is also
selectable.
 The function setting
adjusts the brightness of the backlight.

5.3.

Weight Display Resolution

The weight display resolution is a ratio of the minimum display to the weighing capacity.
The SJ-WP/-BT series has four types of weight display resolution, as shown below.
Low:
1/3,000
Normal:1/6,000 or 1/7,500 (depending on the weighing capacity)High:
1/12,000 or 1/15,000 (depending on the weighing capacity)
Maximum:
1/30,000
The factory setting is the normal resolution. Select the resolution according to your own
application in the function setting.
 For details about the minimum display and the weighing capacity,refer to "14. Specifications".
 The weight display resolution of the Legal for Trade models is fixed. The selection in
the function setting

9. Auto-TareThe SJ-WP/-BT series has an auto-tare function to be used with the comparator mode
enabled. If the weight values are in the OK range of comparator limits and stable for apreset period of time, the scale will automatic 1 ally tare the weight and show zero.
 In some countries or areas, the auto-tare function cannot be used on the Legal for
Trade models and the selection in the function settings,
andis not available.
 To use the auto-tare function, set the function settings below.
: Compare all weighing data (other settings may be used depending on
the application).
: Auto-tare function enabled.
to : Select the timing to tare automatically to avoid the wrong tare operation,for example; too early to tare, to take a longer time to go to the next
weighing.
Normal comparison
 Start with display zero after tare operation. Place or take away objects until thecomparison result will show OK. When the stable indicator is ON for a the preset
period of time specified in the function setting, the scale will automaticallytare the weight, show zero and be ready for next weighing to repeat.

In this setting, the polarity of LOLO, LO, HI, and HIHI limit values are ignored andthe scale shows the comparator results as below.
Note: To start the take-away check weighing, be sure to use the TARE switch totare the weight of the container filled with objects. The ZERO switch may
zero the display, and the scale goes below the zero point by taking out theobjects. Then, the auto-tare function does not work.
 When the function "Tares the initial (container) weight" is selected:
To start the auto-tare function, usually the container (filled with objects) will beplaced on the weighing pan and its weight must be tared using the TARE switch.
When the function
is selected, the scale will tare the initial (container)
weight automatically.
When all load on the weighing pan is removed, the scale will return to the zero point
and the tare weight will be automatically cleared. If the scale does not return to thezero point, press theswitch to clear the tare weight.

 The sensitivity adjustment weight value is equal to theweighing capacity. (factory setting) If SPAN sensitivity adjustment is not to be performed,
turn the power OFF to exit from the sensitivity
adjustment procedure.
5. To adjust with a weight different from the weighing capacity,change the displayed value using the following switches.
MODE
To shift the digit that is blinking to the right.
SAMPLE To increase the value of the blinking digit by one.
 Using a weight with the same value as the weighing
capacity is recommended. If other weights are used,
use one with a value greater than two-thirds of thecapacity.
6. Place the sensitivity adjustment weight with the samevalue as displayed on the weighing pan, and wait for the
STABLE indicator to turn on.
7. Press the TARE switch. The scale adjusts SPAN andis displayed. Then, the display returns to.
To finish the procedure, press and hold theswitchor press the CAL switch. The scale turns the power OFF.
Note: If the scale will be moved to another location, set
the gravity acceleration value for the present
location first and adjust the scale using a weight.
Then, change the gravity acceleration value for the
new location.

31

11.4. Restoring the Sensitivity Adjustment Data to the Factory Set Values
If the gravity acceleration value or sensitivity adjustment data is changed unintentionally,
restore those values to the factory set values, as follows.
