Installation and Precautions
Installation and Precautions
The AD-4406 weighing indicator is a precision electronic instrument. Handle the
indicator carefully.
The operating temperature is -10 to +40 (14 to 104 ).
Do not install the scale in direct sunlight.
Misoperation or other problems may be caused by an unstable power source including
momentary power failrue or instantaneous noise. Use a stable power source.
When AC Adapter is used please confirm 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 electric
power equipment.
Do not install the scale 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 isolators are apt to
be charged with static electricity.
3.1.2.
Power Supply
When the AC adapter is used
A stable power source must be used, since an unstable power source which
includes an instantaneous noise component may result in misoperation.
When dry batteries are used
Use fresh batteries, preferably alkaline type. Insert batteries into the battery box(use
caution in inserting to match the polarity of the batteries), and insert the battery box
with the contacts to the inside of the indicator. Push it in and towards the bottom.
The battery box will hook onto the edge of the case. Install the cover over the
battery box so that it wll not fall out.
To remove the battery box, press in and up on the end of the battery box. Slowly
release pressure on the battery box while holding it against the top of the battery
compartment and the battery box will slide out.
The AD-1681 rechargeable battery pack can be used in place of the standard
battery box.

3.1.3.
The Load Cell Connections
Connect the load cell wires to the connector (receptacle), at the rear panel, using
the accessory load cell plug.
It is possible to connect a 4 wire cable that 1pin-2pin and 3pin-4pin 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 four 350 ohm load cells.
The load cell drive is 5VDC 5% between EXC+ and EXC-, the maximum current 60mA.
3. Installation and Precaution
Adjustment of the Load Cell Output
Caution
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 a large resistance value as possible in the range in
which 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+.
3. Installation and Precaution

3.1.4.
Verifying Load Cell Output and Input Sensitivity
The input sensitivity of the indicator is 0.2uV/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 equivalent to a one division
change of the display. Select as large an input voltage sensitivity voltage
as possible so that the weighing interval becomes stable.
Consider the leverage if a lever is used.

CAL
Writes all the set data into non-volatile memory and displays CALoFF after
which the calibration mode is off with ON/OFF key. Note that ON/OFF does
not function alone. Press ESC while holding ON/OFF to end the calibration
mode when value is mistakenly set. After CAnSEL is displayed pressing
ON/OFF stops calibration mode and turn the unit off.
Caution
The maximum display is less than or equal to 20000 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 another location or the environment
has changed.
It is not necessary to set 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 turned on. 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. Calibration Procedure

Description
In multi-interval scale. The last division is set to maximum ( d-50 ).
Therefore the next division can not be entered.
Resolution exceeds 10000. (Resolution = maximum capacity/ minimum
division)
Reduce maximum capacity or increase 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 (or entering digital input), the value exceeded
maximum capacity. Reduce calibration mass (or digital input).
Selected calibration mass is smaller than minimum division.
New input sensitivity is less than 0.2 µV/division. Increase input sensitivity.
Refer to "3.1.4.Verifying Load Cell Output and Input Sensitivity".
Placing 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.
Load cell output exceeds the input range before maximum capacity.
Adjust zero balance referring to "3.1.4.Verifying Load Cell Output and Input
Sensitivity". Replace with a load cell designed smaller output. Reduce
maximum capacity.
The weighed value is out of the input range at zero calibration or span
calibration. Check the weighing unit and cables.
The last weighing range is larger than next weighing range.
Incorrect mass is selected at the digital linearization function.
Select mass of the following relation. lnr 1 < lnr 2 < lnr 3.
An unacceptable value was selected in the gravity acceleration function.
Exit this error using the Operate/Standby key.

This function can not accumulate different unit data. Specify a unit before use.
Display of Accumulation Data
When setting to CF08 1 (Effective accumulation function) and pressing the key that
allows accumulation display, the totAL is displayed and the total data is
displayed with the M+ mark blinking . A press of the ESC key makes the number
of date accumlated display. And when the ESC key is pressed again, the
weighing data is displayed.
The total data can be output. Refer to "Output of Accumulation Data"
Undoing the Accumulation Data
The last weighing data can be deduced from the accumulation data unless new
data is accumulated.
Step 1 Press the key allocated to function the operation to display totAL and
accumulation data.
Step 2 Press and hold the +/- key more than 3 seconds. The display blinks once and the
last accumulation data before accumlating last weighing data is displayed.
Caution

10. Comparison
This function has the "upper / lower comparison", the "5-stage(HIHI/HI/OK/LO/LOLO)
comparison", the "setpoint comparison" and the "simple batch". They compare the
weighing data with preset parameters and can output the result of the comparison to
the display and beeping, also to the relay-outputs of OP-03 and OP-05.
Set the F-function the F22 and F23 to use the "upper / lower comparison", the
"5-stage(HIHI/HI/OK/LO/LOLO) comparison" (these two comparison will be combined
and be called "Weight check mode" from now), and F22 throgh F26 to use the
"setpoint comparison" and the "simple batch".
There are four code memories for the setpoints. Data is stored in the EEPROM,and is
not lost even if the AC power supply is disconnected or battery is empty.
Code memory is changed by the key switch, external control input, or the command
via serial interface.
10.1. Weight Check Mode
This function compares the weighing data with the upper limit value and lower limit
value(upper/lower limit comparison) or four limit values(HiHi, Hi, Lo and LoLo), and
indicates, beep and/or outputs the result to the three relays of HI, OK and LO. Use this
comparison when judging whether a weight is proper.
Set to the F-function F22 1, 2, 3 to use upper/ lower limit comparison and F22 4, 5, 6
to use 5-stage comparison.
Select a parameter of the F-function F23 for the comprison condition.
Specify the upper and lower limit / HiHi, Hi, Lo, LoLo limit values.
When inputting the lower limit value(s), it is not necessary to input the F-function F22
and F23 again unless changing the F-function.
3 type of setting values for each comparison.
1) Set limit value (upper limit and lower limt / HiHI, Hi, Lo, LoLo limit).
2) Set Target value and acceptable tolerance(upper and lower) in weight.
Limit value is calculated automaticcly.
3) Set Target value and acceptable tolerance(upper and lower) in percentage of the
target weight. Limit value is calculated automaticcly.
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 minus value
3) TG(Target) : 50 (kg), Hi(Upper acceptable tolerance) : 2 (% of Target),
Lo(Lower acceptable tolerance) : 4 (% of Target) not minus value

Page 37
10.1.1. Condition formula for Comparison
Comparison is performed based on the following formula.
State Name
Condition Formula
HiHi *
HiHi limit value < Display value
HI
Upper limit (Hi limit) value < Display value
OK
Lower limit value
Display value
Upper limit value
LO
Display value < Lower limit (Lo limit) value
LoLo *
Display value < LoLo limit value
* HiHi and LoLo is 5-stage comparison only
The decimal point is not considered. Example: If the upper limit value is 10.0, input 100.
These parameters are stored in the EEPROM, and are not lost even if the AC
power is disconnected or the batteries are empty.
When the display value becomes an over load (positive over), HI (over) is outout.
When the display value becomes an under load (negative over), LO (under) is output.
This function compares the upper limit value first.
This function does not check the relation of upper limit value and lower limit value.
10.1.2. Setting Upper/Lower Limit Values
Step 1
With the setting setpoint function key, that function is allcated, "SEt Pt" display
will appear. Lerease the key switch, it cahnges to setting the setpoint mode and
display code memory number blinking.
Step 2
Set memory code number using following keys.
key ..... The key to select a comparison class and proceed to step 3.
key ..... The key to select a code memory number.
ESC key. The key to return to weight display with out code memory change.
ENTER key. The key to set displayed code memory's setpoint and return to
weight display.
Step 3
Select the comparison class(upper limit value etc.) using the following keys.
key ..... The key to select a comparison class (flashing).
ESC key ..... The key to go back to step 2.
ENTER key. The key to proceed to step 4.
Step 4
Set the setpoint value using the following keys.
key ..... The key to select a figure.
key ..... The key to select a number.
ENTER key The key to store the parameter and go back to step 3.
ESC key ..... The key not to change the parameter and go back to step 3.
