Page 4 AD-4329A Weighing Indicator
2. Introduction
The AD-4329A is a compact weighing indicator that amplifies the signal 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/division.
Maximum display: ...................... 10000 divisions (or 20000 divisions).
Refresh rate of the display:........ 10 times/second approximately.
Input voltage range:................... -35 mV ~ +35 mV.
There are the following standard functions:
The upper/lower limit comparison to check a mass value.
The setpoint comparison for batching applications.
The accumulation function to totalize these mass values and to count the
number of accumulations.
There are the following standard interfaces:
The standard serial output for a printer.
The RS-232C serial interface to communicate with a computer.
This interface can request weighing data, enter parameters and control the state
of the indicator.
The calibration function includes the following functions:
Setting of the minimum division (weighing interval) and the maximum capacity.
Zero and span calibration.
The weighing range function of the multi-interval weighing instrument (scale).
Digital linearization function.
Gravity compensation function.
There are seven external input terminals controlled by the F function.
The option OP-02 has three output relays used for the upper/lower limit comparison
and setpoint comparison.
