2. Introduction

Page 6AD-4407A Weighing Indicator3. Installation and Precautions
3.1.

Installation and Precautions

The weighing indicator is a precision electronic instrument. Handle it carefully.
The operating temperature is -10°C to +40°C (14°F to 104°F).
Do not install the scale in direct sunlight.
Mis-operation or other problems may be caused by an unstable power source including
momentary power failure or instantaneous noise. Use a stable power source.
Do not connect the power cord before the installation has been completed.
Verify that the local voltage and receptacle type are correct for your indicator.
Use shielded cables for all connections. Connect the cable shields to the shieldterminal or case as an earth terminal.
Earth ground the indicator. Do not share the earth ground line with other electrical
power equipment. (Example: There is an earth ground terminal at the power cord receptacle.)
Do not install the indicator in a place where it is apt to be charged with static
electricity, or where the relative humidity is lower than 45%RH. Plastic andinsulating materials are apt to be charged with static electricity.
Even if the display is turned off, the power is on while the power cord is connected to
the AC power source.
Even if the indicator complies with IP-65, do not immerse the indicator in water.
To maintain water-proof performance, tighten the cable clamp firmly when connecting
the load cell cable or interface cable. And tighten the bolts on the rear panel firmly.
The recommended torque is 1Nm.

3.2.

Load Cell Connections

Connect the load cell cable to the terminal as shown below.
It is possible to connect a 4 wire cable provided that pins 1-2 and pins 3-4 areconnected, if the distance between the indicator and a load cell is shorter than
5m. At this time, use a cable with a wire having a cross-sectional area of 0.5mm2 or greater because thin cables will decrease the temperature coefficient.
The output voltage of a load cell is a very sensitive signal. Space the load cell
cable away from any noise source.
It is possible to connect eight 350ohm load cells.
The load cell drive is 5VDC
5% between EXC+ and EXC-, the maximum
current 120mA.

3. Installation and Precautions

3.3.
CautionAdjustment of the Load Cell Output

When adding a resistor to adjust a load cell output, use a metal film
resistor in the range of 50kohm to 500kohm with a good temperature
coefficient. Use as large of a resistance value as possible in therange in which the zero adjustment is possible. Solder this resistor
at a point near the load cell or the indicator.

In Case of Reducing the Output Voltage
When the zero output is too large, add a
resistor between EXC+ and SIG-.

In Case of Adding an Offset Voltage to the Output
When the zero output is too small, add a
resistor between EXC+ and SIG+.

Verifying Load Cell Output and Input Sensitivity

The input sensitivity of the indicator is 0.15 µV/division or more. Satisfy the following
inequality, when you design a weighing instrument using the indicator and load cell(s).
A change in input voltage sensitivity is required to cause a one
Cautiondivision change of the display. Select as large an input sensitivity
voltage as possible so that the weighing interval becomes stable.
Consider the leverage if a lever is used.

Page 12AD-4407A Weighing Indicator5. Calibration
This indicator, converts an input voltage from a load cell to the "mass" value, anddisplays it. Calibration is the adjustment function so that the scale (indicator) can
display the weight correctly.

5.1.

Items of Calibration Mode

There are four items in the calibration mode.
How to enter the calibration mode:
In the weighing mode, press the CAL key. After Cal in is displayed for 2
seconds Cal 0 will appear. Then the required items should be selected anddisplayed with the MODE key, then executed by pressing ENTER key.
Note: Calibration could be started by simultaneously pressing the ZERO and TARE
key, instead of CAL key. The procedure is prohibited when the indicator hasreceived a certified approval.
Items Required to be Performed
Cal 5etSets capacity, resolution, decimal point position and display format,
weighing range and unit. These items should be input first in order for
the indicator to function as a weighing instrument. These parameters
do not need to be changed again unless the indicator itself is replaced.
For details, refer to “5.2.1.Configuring a Weighing Instrument”.
Cal 0
Calibrates zero and span. This is required after installation, to get
accurate data. For details, refer to “5.2.3. Zero Calibration” and “5.2.4.
Span Calibration”.
Optional Items to be Performed as Necessarylnr 0
Performs digital linearization. Refer to “5.4.Digital Linearization
Function”.
g 5etCompensates for acceleration of gravity. Refer to “5.5. Gravity
Compensation Function”.
Gravity compensation function: Compensates for weighing error
between the calibration location and other weighing location using
gravity acceleration.
In the calibration mode, the keys have functions as follows:
0 - 9 Numerical keys.
MODE The key to display other items.
CLEAR The key to restore the numerical value to the initial setting or to change
the parameters.
+/The key to display other parameters.
ESC
The key to proceed to the next step without changing the parameters.
ENTER The key to store new calibration data and proceeds to the next step.

The maximum display is less than or equal to 40000 divisions. This
number is calculated from the maximum capacity divided by theminimum division.
Check the accuracy of weighing instrument periodically.
Recommended mass, use a mass heavier than 2/3 maximum
capacity.
Calibrate the scale, if it is moved to other location or theenvironment has changed.
It is not necessary to input the gravity acceleration correction, whencalibrating the scale with a calibration mass at the place where thescale is used.
Enter the stable weight data while the STABLE mark is displayed. If
unstable data is used, it may cause a weighing error. Arrange thecondition using the F00 filter function.
The span calibration needs the zero calibration data. We recommendthat you perform the span calibration immediately after the zero
calibration.
If you use the dual range function of the multi-interval scale, performthe "Range Function", "Zero Calibration" and "Span Calibration".

Weighing Range Function

In the weighing range function, select "single range" and "dual range". Specify
each weighing interval (division) for the multi-interval instrument. Each weighinginterval is displayed according to a net value or gross value.
CautionWhen single range is used, this function is not used.

Example 1

Selecting the Division and Range

Consider the following rules to design the weighing range.
Rule 1 Select the division and range of each weighing range so as to satisfy the following
inequality.
The first range < the second range
The division of the next weighing range is automatically set larger than thedivision of the lower weighing range. Changing the division is possible.
Rule 2 When specifying the dual range, the upper limit value of the second range
becomes the maximum capacity.
Rule 3 Select a resolution smaller than 40000. The resolution is a value obtained by
dividing the maximum capacity by the minimum division of the first range.

5.4.

Digital Linearization Function

Even if the zero and span calibration have been completed, there may still
remain a linearity deviation caused by the performance of the weighing unit.
The digital linearization function can rectify or reduce the linearity deviation
using weighing points except zero and capacity. Up to three weighing points
can be specified.
CautionThis function does not improve repeatability or hysteresis.
Use the mass on the condition that lnr 1 < lnr 2 < lnr 3.
Do not press the ENTER key while the STABLE mark is off.

Step 1 When Cal 0 is displayed, press the MODE key to display lnr 0 .
Step 2 Enter the zero point. Refer to “5.2.3. Zero Calibration”.
Step 3 The value of the middle point is displayed after indicating lnr x . x is 1, 2 or 3.
The triangle
mark of the same number(x) is displayed along with the value.
Step 4 Select a middle point.
If you want to cancel the current procedure, press the ESC key to finish thisfunction. Proceed to step 7 and other points are cleared (canceled).
Select a middle point value using the 0 - 9 keys. Proceed to step 5.
Step 5 Place a mass equivalent to the displayed value on the weighing unit. Wait for
the STABLE mark to turn on and press the ENTER key. Proceed to step 6.
Step 6 If you include a 2nd and 3rd middle point, repeat steps 3, 4, 5 for each point.
If you finish this function, proceed to step 7.
Step 7 Perform step 11 of "5.2.4. Span Calibration" immediately.

Gravity Compensation Function

If the scale is used at the calibration location, it is not necessary to perform thisfunction.
If there is a difference of gravity acceleration between the installed locationand calibration location, it may cause a weighing error. This function specifies
these gravity accelerations and corrects the span error.
Note

The decimal point is not displayed in the function. Example: 9798 = 9.798 m/s2
When span calibration is executed, the gravity acceleration correction
will be cleared and the two gravity acceleration values will return to thefactory settings.

Step 1 At the Cal 0 display, press the MODE key until g 5et is displayed andpress the ENTER key to enter the gravity compensation function.
If you want to cancel the current procedure, press and hold the ON/OFF key andpress the ESC key to display CanCel . Then, no parameters are changed andthe calibration mode is finished. Press the ON/OFF key to turn the display off.
Step 2 The parameter is displayed with triangle
1. Enter the gravity acceleration of thecalibration location using the 0 - 9 keys. The parameter xxxx is the gravity
acceleration.
ENTER key ..The key to store the new gravity acceleration and proceed to step 3.
ESC key ... The key to return to g 5et without changing the value.

Step 3 The parameter is displayed with triangle
2. Enter the gravity acceleration of theinstalled location using the 0 - 9 keys. The parameter xxxx is the gravity
acceleration.
ENTER key ..The key to store the new gravity acceleration and proceed to step 4.
ESC key ... The key to return to step 2 without changing the value.
Step 4 Now g xxxx is displayed. Press the CAL key to store the parameters. The
Caloff is displayed. Proceed to step5.
Note: Caloff can be displayed by pressing the +/- key while pressing the
ON/OFF

key, instead of CAL key.

Step 5 Press the ON/OFF key to turn the display off.

Description
In multi-interval scale. The last division is set to maximum ( d-50 ).
Therefore the next division can not be entered.
Resolution exceeds 40000. (Resolution = maximum capacity/ minimum
division) Reduce the maximum capacity or increase the minimum division.
The load cell output is too large or too small at zero calibration. Check theweighing unit and load cell. Refer to "3.4. Verifying Load Cell Output and Input
Sensitivity".
The calibration mass value exceeded the maximum capacity. Use thecalibration mass less than the maximum capacity.
The selected calibration mass is smaller than the minimum division.
The new input sensitivity is less than 0.15 µV/division. Increase the input
sensitivity.
Refer to "3.4. Verifying Load Cell Output and Input Sensitivity".
When a mass is placed on the weighing unit, the load cell output becomes anegative value. Check the load cell cable connections and the direction of loadcell mounting.
The load cell output exceeds the input range before reaching the maximum
capacity. Adjust zero balance referring to "3.4. Verifying Load Cell Output andInput Sensitivity". Replace with a load cell designed for a smaller output. Or
reduce the maximum capacity.
The weight value is out of the input range at zero calibration or spancalibration. Check the weighing unit and cables.

This function has the "upper / lower comparison", the "5-stage(HiIHi / Hi / OK / Lo /LoLo) comparison", the "setpoint comparison" and the "simple batch". They compare
the weight data with preset parameters and can output the result of the comparison to
the display and buzzer, also to the relay-outputs of OP-03, OP-05 and OP-08.
Set the F-function f22 and f23 to use the "upper / lower comparison", the"5-stage(HiHi / Hi / OK / Lo / LoLo) comparison" (these two comparison methods
will be combined and hereafter be called the "Weight check mode"), and f22
through f26 to use the "setpoint comparison" and the "simple batch".
There are four code memories for the setpoints. Data is stored in non-volatilememory and is not lost even if power is turned off.
Code memory can be selected by key switch, external control input, or a command
via the serial interface. Refer to “13.3. Command Format”.

10.1. Weight Check Mode
This function compares the weight data with the upper and lower limit values(upper/lower limit comparison) or with four limit values of HiHi, Hi, Lo and LoLo
(5-stage comparison), and displays, sounds the buzzer and outputs the results tothe three relays of HI, OK and LO. Use this comparison when judging whether aweight is proper.
Set the F-function f22 to 1, 2 or 3 to use upper/ lower limit comparison and f22 to4, 5 or 6 to use 5-stage comparison.
Select a parameter of the F-function f23 for the comparison condition.
Set the F-function f26 (zero band) if f23 is set to10 (not to compare in the zero band).
Specify the upper and lower limit / HiHi, Hi, Lo, LoLo limit values.
When entering the limit value(s), it is not necessary to enter the F-function f22 andf23 again unless comparison conditions are changed.
There are 3 type of limit values for each comparison.
(1) Set the limit value (upper and lower limit / HiHi, Hi, Lo, LoLo limit).
(2) Set the Target value and an acceptable tolerance(upper and lower) in weight.
The limit value is calculated automatically.
(3) Set the Target value and an acceptable tolerance(upper and lower) inpercentage of the target weight. The limit value is calculated automatically.
Example. Target = 50 kg, Upper limit = 51 kg, Lower limit = 48 kg(1) Hi (Upper limit) : 51 (kg), Lo (Lower limit) : 48 (kg)(2) TG (Target) : 50 (kg), Hi (Upper acceptable tolerance) : 1 (kg),Lo (Lower acceptable tolerance) : 2 (kg) not negative value(3) TG (Target) : 50 (kg), Hi (Upper acceptable tolerance) : 2 (% of Target),
Lo (Lower acceptable tolerance) : 4 (% of Target) not negative value

11. Hold Function

12. Counting Function
This function determines the number of objects in a sample based on the unit
weight. The unit weight is stored as one of the code memory data in non-volatilememory, and is not lost even if power is turned off.

12.1. Using the Counting Function
Set f07 to1 in the F-Functions.
Select the code memory number. Refer to “9.1. Using Code memory”.
Register the unit weight. Refer to “12.2.Unit Weight Registration”.
Press the MODE key to enter the counting mode. The unit in the display
changes to pcs.
In the counting mode, TARE, ZERO, NET/GROSS and other operations are thesame as that in the normal weighing mode.

12.2. Unit Weight Registration
There are three methods to register the unit weight: By weighing the actual
samples to determine the unit weight, by digital input of the unit weight, or bycommand via the serial interface.
The unit weight is one item of the code memory data. Select the code memory
number and start the unit weight registration in the counting mode. The unit
weight registration can not be done from the code memory number display.
The counting accuracy improvement function by re-calculating the unit weightbased on the actual weight is not available..
Weigh Actual Samples
When the unit weight is unknown, prepare some samples to determine the unit
weight.
Step 1 Enter the counting mode.
Step 2 Press the SAMPLE key to enter the unit weight registration mode. 5 0
or 5 - is displayed and unit pcs blinks. the left side of the display is thenumber of samples. The right side of the display indicates the weight, 0means that the weight is zero and - means that the display is not at zero.
Step 3 Select the number of samples and place the samples specified on the weighing
unit. Use the following keys:
0 - 9 key ......... The key to set the number of samples. Maximum is 9999.
+/- key ................. The key to select the number of samples, 5, 10, 20, 50,100.
ZERO key ........... The key to set the zero point.
TARE key ............ The key to tare, when using a container.
Page 46
12. Counting Function

AD-4407A Weighing IndicatorENTER

key ......... The key to register the unit weight and return to thecounting mode. The unit weight is calculated automaticallywith the weight and the number of samples.
Press ESC key while pressing the +/- key
The key to return to the counting mode without changing
the unit weight.
Notes

It is preferable to have a large number of samples, to minimize thecounting error.
Press the ENTER key after the STABLE mark turns on.
If the total weight of the samples is too light and is not adequate to
be used as the unit weight, loUt is displayed for 2 seconds andreturns to the registration display.

Digital Input
When the unit weight is known, digital input is available.
Step 1 Start with the normal weighing mode.
Step 2 Press the SAMPLE key. U xxx and the unit weight is displayed with unit
pcs blinking. Use the following keys:
0 - 9 key......... The key to set the unit weight. Maximum is 5 digits.
+/- key................. The key to select the weight unit of the unit weight.
key ........... The key to clear the digital input. U---- is displayed.
ESC key .............. The key to return to the the weighing mode without
ZEROchanging the registered unit weight.
ENTER key ......... The key to register the unit weight and return to theweighing mode.
Press the MODE key while pressing +/- key….The key to shift thedecimal point.
Command Input
When the unit weight is known, command input via the serial interface isavailable. For details, refer to “13.3. Command Format”.

17. Current Loop Output (OP-08)

Current Loop Output
The current loop output can be used to output the data to an A&D printer and adisplay unit.
The current loop output is of the passive type and requires an external current
source of 20 mA current. A&D’s printer and display unit can be connected without
an external power source, because they supply the current.
The output terminals do not have a polarity. Each output terminal can be connected
to either the plus or minus inputs of the peripheral unit.
Set f36, f37, f38 and f39 of F-Functions. Please note the initial setting of f37 isdisabling the current loop output.
Data format
The data format is the same as that of the initial setting of f34 of RS-232C data
format.
The current loop output data format is fixed and can not be changed.
The header 2 and the unit selection are common to RS-232C (Cf06, Cf07).
