1. Cautions
Installation and Precautions
1.1.
Before use, confirm the following articles for safe operation.
Avoid vibrati on, shock, extr emely high tempe rature and humi dity, direct sunlight,
dust, splashing water, air containing salt or corrosive gases, places where
inflamma ble gases are p resent.
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.
W hen extending the load cell cable, separate it from the power cable and
electrica l cables with m uch noise.
Do not turn on the module unt il installatio n is complete. Th e 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-4430B.
Use a shielded load cell cable.
Do not connect more sensors than the allowable number noted in the
specifications.
Cautions During Use
1.2.
The AD-4430B is a precision instrument that measures microvolt output from load
cell. Prevent noise sources such as power lines, radios, el ectric welders or motors
from affecting the instrument.
Do not disassemble the AD-4430B.

depends on specifications of the weighing system.
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

this by using the check mode.
Use an appropriate calibration weight and

Digital lin earization is t he non-linearit y compensation f unction 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.
