During a stable measurement, the
LED lights.
The decimal point flashes in calibration mode.
6.1. Span Calibration using Mass
Preset a unit, decimal point, minimum division and weighing capacity in function
mode. The span calibration is performed using mass of the weighing capacity.
When
and a number are displayed, an error has occurred. Refer to
"Calibration Errors" for details.
The flashing decimal point means "no weighing value".
Before the calibration, turn on the AD4430B more than 10 minutes so as to
avoid temperature drift (change).

6.2. Calibration Errors
Display
Cause Treatment
Resolution (Weighing
capacity / minimum division)
exceeds the limitation.
Make the minimum division greater or make the
weighing capacity smaller. The specified value
depends on specifications of the weighing system.
The voltage in zero
calibration is too large.
The voltage in zero
calibration is too small.
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.
Mass value exceeds the
weighing capacity.
Mass value is too light for
calibration.
Use an appropriate calibration weight and
calibrate again.
Sensitivity of the load cell is
too small.
Use a load cell with higher sensitivity or make
the minimum division greater.
The polarity of the load cell
output is reversed.
Check the load cell connection.
The output of the weighing
capacity is out of range.
Use a load cell with a greater rating or make the
weighing capacity smaller.

2. Cautions
2.1. Installation and Precautions
The module complies class A computing device pursuant to Subpart J of Part 15
of FCC rules. (FCC = Federal Communications Commission in the U.S.A.)
The module complies the statutory EMC (Electromagnetic Compatibility)
directive 2004/108/EC and the Low Voltage Directive 2006/95/EC for safety of
electrical equipment designed for certain voltages for European Directives.
The module is a precision electronic instrument. Handle it carefully.
Avoid vibration, shock, extremely high temperature and humidity, direct sunlight,
dust, splashing water and air containing salt or sulfurous gases.
Avoid places where inflammable gases or vapors are present.
The operating temperature is -10°C to +50°C (14°F to 122°F).
Ground the module and DIN rail.
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.
Use a shielded load cell cable.
Do not connect more sensors than the allowable number noted in the
specifications.
2.2. Cautions During Use
The AD-4430B is a precision instrument that measures microvolt output from
sensors. Prevent noise sources such as power lines, radios, electric welders or
motors from affecting the instrument.
Do not disassemble the AD-4430B.
In all hold modes, the hold data is saved digitally, so there is no drooping of the
value displayed on the display panel or the analog output. Note that the hold
function is disabled when the AD-4430B is disconnected from the power supply.
