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.
