A&D Weighing Indicator AD-4329 - Manual (Page 6)

2. Introduction
□ The AD-4329 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.
a This indicator has the following performance:
Input sensitivity:........... ............... ...0.2juV/division.
Maximum display:.................. ........10000 divisions (or 20000 divisions).
Refresh rate of the display:.............. 10 times/second approximately.
Input voltage range:........................-1 mV ~+15 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.
a There are the following standard interfaces:
□ The standard serial output for a printer.
Q 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.
a 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,
o The option OP-02 has three output relays used for the upper/lower limit comparison
and setpoint comparison.
