3. Installation and Precautions
3.1.1.
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 scale.
Use shielded cable for all connections. Connect the cable shields to the shield
terminal or case as an earth terminal.
Earth ground the indicator. Do not join 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 and insulating
materials are apt to be charged with static electricity.
3.1.2.
The 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 are
shorted, if the distance between the indicator and a load cell is shorter than 5m.
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.

3.1.3.
Caution
Adjustment of the Load Cell Output
Use a metal film resistor in the range of 50kohm to 500kohm with a
good temperature coefficient, when adding a resistor to adjust a load
cell output. Use as large of a resistance value as possible in the range
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 0.25mV /division or more. Adapt to the following
inequality, when you design a weighing instrument using the indicator and load cell(s).
Caution
A change in input voltage sensitivity is required to cause a one division
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.

5. Calibration
This indicator, converts an input voltage from a load cell to the "mass" value, and
displays it. Calibration is the adjustment function so that the scale (indicator) can
display the weight correctly.
5.1.1.
Items of Calibration Mode
There are four items in the calibration function in the procedure.
How to calibrate: In 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 and
displayed 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. However, in some cases, the procedures are altered to nullify this
option. Furthermore, this option is not available with Stamping type version setting.
Required Items
Cal 5et
Store capacity, resolution, alignment of 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 (Sub-functions)
lnr 0
Performs digital linearization. Refer to “5.4.Digital Linearization
Function”.
g 5et
Compensates 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 cancel key at inputting data, initial data and changing mode.
+/ESC
ENTER
CAL
The key to display other parameters.
The key to proceed to the next step without changing them.
The key to store new calibration data and proceeds to the next step.
The key to store all data into memory and display Caloff after the
calibration mode. And press the ON/OFF key to turn off the display.
AD-4407 Weighing Indicator
Page 11
5. Calibration
Note that the ON/OFF key does not function alone. Press the ESC key while
holding the ON/OFF key to end the calibration mode, if mis-operation. After
displaying Can5el, press the ON/OFF key to stop calibration mode and to
turn the indicator off.
NOTE: When displaying Caloff , press the +/- key while pressing the ON/OFF key,
instead of CAL key.
Caution
The maximum display is less than or equal to 40000 divisions. This
number is calculated from the maximum capacity divided by the
minimum 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 the environment
has changed.
It is not necessary to input the gravity acceleration correction, when
calibrating the scale with a calibration mass at the place where the
scale is used.
Enter the stable weighing data while the STABLE mark is displayed. If
unstable data is used, it may cause a weighing error. Arrange the
condition using the F00 filter function.
The span calibration needs the zero calibration data. We recommend
that you perform the span calibration immediately after the zero
calibration.
If you use the dual range function of the multi-interval scale, perform
the "Range Function", "Zero Calibration" and "Span Calibration".
5.2.

Weighing Range Function
The weighing range function can select "single range" and "dual range". Specify each
weighing interval (division) for the multi-interval instrument. Each weighing interval is
displayed according to a net value or gross value.
Caution
When single range is used, this function is not used.
Example 1

5.3.1.
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 fit the following inequality.
The first range < the second range
The division of the next weighing range is automatically set larger than the division
of the lower weighing range. And the division can change.
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 that divides 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 during the zero and capacity. Up to three weighing points can be
specified.
Caution
This function does not improve repeatability or hysteresis.
Use the mass on the condition that lnr 1 < lnr 2 < lnr 3.
3
Do not press the ENTER key while the STABLE mark is off.
Step 1 Check the Cal 0 display. Press the MODE key to display lnr 0 .
Step 2 Enter 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 this
function. 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. Press the
ENTER key after the STABLE mark has turned on. Proceed to step 6.
Step 6
If you include a 2nd and 3rd middle point, repeat steps 3, 4, 5 for each.
If you finish this function, proceed to step 7.
Step 7
Perform step 11 of "5.2.4. Span Calibration" immediately.

Gravity C
Compensation
ompensation Function
If the scale is used at the calibration location, it is not necessary to perform this function.
If there is a difference of gravity acceleration between the installed location and
calibration location it may cause a weighing error. This function specifies the
gravity acceleration 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 the factory
settings.
Step 1
At the Cal 0 display, press the MODE key until g 5et is displayed and press the
ENTER key to enter the gravity compensation function.
If you want to cancel the current procedure, press and hold the ON/OFF key and press
the ESC key. Then, no parameters are changed and the calibration mode is finished.
Press the ON/OFF key to turn the display off after displaying CanCel.
Step 2
The parameter is displayed with triangle
1. Enter the gravity acceleration of the
calibration 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 the
installed 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: When displaying Caloff , press the +/- key while pressing the ON/OFF key,
instead of CAL key.

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.
Load cell output is too large or too small at zero calibration. Check the weighing
unit and load cell. Refer to "3.1.4.Verifying Load Cell Output and Input
Sensitivity".
Measuring calibration mass, the value exceeded maximum capacity. Reduce
the calibration mass.
The selected calibration mass is smaller than the minimum division.
The new input sensitivity is less than 0.2 mV/division. Increase the input
sensitivity.
Refer to "3.1.4.Verifying Load Cell Output and Input Sensitivity".
Placing a mass on the weighing unit, the load cell output becomes a negative
value. Check the load cell cable connections and the direction of load cell
mounting.
The load cell output exceeds the input range before reaching the maximum
capacity. Adjust zero balance referring to "3.1.4.Verifying Load Cell Output and
Input Sensitivity". Replace with a load cell designed for a smaller output.
Reduce maximum capacity.
The weight value is out of the input range at zero calibration or span
calibration. Check the weighing unit and cables.

10. Comparison
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".
Data is stored in non-volatile memory and is not lost even if the AC power supply is
disconnected or cut off.
10.1. Weight Check Mode
This function compares the weight data with the upper and lower limit values
(upper/lower limit comparison) or four limit values of HiHi, Hi, Lo and LoLo (5-stage
comparison), and displays, sounds the buzzer and/or outputs the results to the three
relays of HI, OK and LO. Use this comparison when judging whether a weight is
proper.
Set the F-function f22 to 1, 2 or 3 to use upper/ lower limit comparison and f22 to 4, 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 10 (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 and
f23 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) in
percentage of the target weight. The limit value is calculated automatically.
Example. Target = 50kg, Upper limit = 51kg, Lower limit = 48kg
(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
This function displays the hold weight data after averaging the weight data for a
specific period.
Useful to determine a living animal’s weight.
Averaging time can be set up to 9.9 seconds by a 0.1 second step.
3 methods are available to start averaging; manual start, start automatically after
stable and manual / automatic start.
Manual start is available with key switch or external input.
Serial interface commands are also available; averaging start, releasing the hold
data and outputting the hold state. Refer “13.3.4. Commands for Hold Function”.
This function can not be use under Cf00 1.

Averaging can not start at a displayed value smaller than +/- 5 digits.
Data when the display is over is not included for averaging.
When powered off, hold is released automatically.
Caution
There is no peak hold function.
The Display and the Data Output of Hold and Average
The weight display is blinking during the averaging period.
The output data in the averaging period is the actual weight at the time.
The weighing unit is blinking when the weight display is in the hold state.
The output data format of the hold weight data is the same as that of the normal
weight data except the header of stable state is “HD” in the response to the “RW”
or “RW,n”(n=1 or 2) command.
Relations to the Other Functions
If automatic accumulation (f20 21) and/or auto print (f37 2, 3 f40 2, 3) is set,
accumulation and/or data output is performed after determining the hold data.

12. Counting Function
This function determines the number of objects in a sample based on the unit
weight. Unit weight is stored one of the code memory data in non-volatile memory,
and is not lost even if the AC power supply is disconnected.
12.1. Using the Counting Function
Preparation : Set f07 1 in the F-Functions.
Selects code memory number. Refer to “9.1.1. Using Code memory”.
Register the unit weigh. Refer to “12.2.Unit Weight Registration”.
Press the MODE key to enter the counting mode. The unit in the display changes
to pcs.
pcs
In the counting mode, TARE, ZERO, NET/GROSS and other operations are the same
as that in the normal weighing mode.
12.2. Unit Weight Registration
There are two methods to register the unit weight. One is to weigh the actual samples
for an unknown object's unit weight and the other way by digital input of the unit
weight by key or 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 weight display or piece count
display. The unit weight registration can not be done from the code memory
number display.
There is not the counting accuracy improvement function by re-calculating the
unit weight based on the actual weight.
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. 5 0 or 5 is displayed and unit pcs blinks. the left side of the display is the number of
samples. The right side of the display indicates the weight, 0 means 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
sensor unit. Using 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.

The key to return to the piece count display without changing
the unit weight.
Notes
It is preferable to have a large number of samples, to minimize the
counting error.

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 is
disabling 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).
