1. Cautions
1.1. Installation and Precautions
Before use, confirm the following articles for safe operation.
Avoid vibration, shock, extremely high temperature and humidity, direct
sunlight, dust, splashing water, air containing salt or corrosive gases, places
where inflammable gases are present.
The operating temperature is -10°C to +50°C (14°F to 122°F).
Ground the module.
Keep cables away from power cables and other sources of electrical noise.
Use a stable DC24 V power source that does not include step down voltage
and noise.
Do not share the earth ground line and power line with other electrical power
equipment.
When extending the load cell cable, separate it from the power cable and
electrical cables with much noise.
Do not turn on the module until installation is complete. The module is not
equipped with a switch to turn off.
After the installation is complete, take off the protective cover prior to turning on
the AD-4430A.
Use a shielded load cell cable.
Do not connect more sensors than the allowable number noted in the specifications.
1.2. Cautions During Use
The AD-4430A is a precision instrument that measures micro-volt output from load

Step 9 Press the key to return to weighing mode.
4.2. Digital Linearization ( )
Digital linearization is the non-linearity compensation function that can rectify or
reduce linearity deviation between zero point and weighing capacity.
Up to four points can be specified except zero. (Refer to )
Relationship of points : Zero = < < < <
The high-order correction curve is used so that zero point and individual points
are arranged in a straight line.
Digital linearization includes span calibration.
Step 1 When turning off the display using pressing and holding the key,
press the key and the key ( + key). Then of
calibration mode is displayed. Press the key to display .
Step 2 Press the key to select and press the key to enter
digital linearization.

Step 4 While LED is displayed, press the key to store the weighing
value. Then is displayed for 2 seconds.
Step 5 When displaying , press the key to select a weight value.
Specify it using the and key.
Step 6 Place the weight on the pan. While LED is displayed, press the
key to store the weighing value. Then is displayed for 2 seconds.
Step 7 is displayed. Repeat the same operation as Step 5 and Step 6 at
the second point.
Step 8 is displayed. Repeat the same operation as Step 5 and Step 6 at
the third point.
Step 9 is displayed. Repeat the same operation as Step 5 and Step 6
at the fourth point.
Step 10 is displayed. Press the key to store new parameters into
nonvolatile memory (FRAM) and display .
Step 11 Press the key to return to weighing mode. Remove all of weight
from the pan.
4.3. Calibration Errors ( )
Display Cause Treatment
The display resolution
(maximum capacity / minimum
division) exceeds the specified
value.
Make the minimum division greater or
make the weighing capacity smaller. The
specified value depends on specifications
of the weighing system.
Voltage at zero calibration
exceeds in the positive direction.
Voltage at zero calibration
exceeds in the negative
direction.
Check the load cell rating and
connection. When nothing is wrong with
the rating and connection, adjust the load
cell output. When the load cell or A/D
converter may be the cause of error,
confirm this by using the check mode.
The value of the calibration
weight exceeds the maximum
capacity.
The value of the calibration
weight is less than the minimum
division.
Use an appropriate calibration weight
and calibrate again.
The load cell sensitivity is not
sufficient.
Use a load cell with higher sensitivity or
make the minimum division greater.
Voltage at span calibration is less
than voltage at the zero point. Check the load cell connection.
The load cell output voltage is too
high when the mass of
maximum capacity is weighed.
Use a load cell with a greater rating or
make the weighing capacity smaller.

4. Calibration
The AD-4430A measures the voltage of the load cell and displays it. Calibration corrects
the signal from the load cell to convert into mass correctly.
※ Specify "decimal point position ( )", "minimum division ( )" and "weighing
capacity ( )" in function mode.
※ Calibrate (adjust) "input voltage at zero ( )", "span calibration input voltage ( )"
and "weight against span calibration input voltage( )" using the "span calibration using
mass ( )" in calibration mode. These items can be also inputted using "digital span" in
function mode.
※ Perform stable measurement in the calibration to prevent measurement error.
※ During a stable measurement, the LED lights.
※ The flashing decimal point means "no weighing value" in calibration mode.
※ When and a number are displayed, an error has occurred.
Refer to "Calibration Errors" for details.
※ Before the calibration, turn on the AD-4430A more than 10 minutes so as to avoid
temperature drift (change).
