AD-4430B - 5 -

2. Outline and Features

The AD-4430B has the following features.

The weighing module is a weighing indicator that amplifies signals from a load cell, converts it

to digital data and displays it as a mass value.

This indicator has the following performance :

Input sensitivity :

............................

0.15 μV / d (d = minimum division)

Display resolution :

........................

99,999 d in maximum

Sampling rate :

...............................

1000 times/second

Input voltage range :

......................

-35 mV to +35 mV (-7 mV/V to +7 mV/V)

The calibration using gravity acceleration correction :

The function compensates for weighing error due to the difference of gravity acceleration

between the calibration place and the measurement place.

The digital linearization function :

The digital linearization function can rectify and reduce the linearity deviation using weighing

points during the zero and capacity setting. Up to four weighing points can be specified. The

high-order correction curve is used between each points.

Digital span mode :

Keying in the load cell output voltage (mV/V) allows calibration to be performed without an

actual load.
