Introduction
Introduction Introduction Introduction
The AD-4406 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: ......................... 0.2 µV/division
Maximum display: ...................... 40000 divisions
Refresh rate of the display: ........ 10 times/second approximately
Input voltage range: ................... -1 mV to +15 mV
The following standard functions are available:
The HiHi/Hi/OK/Lo/LoLo limit comparison to check a mass value.
The setpoint comparison for batching applications.
There are four code memories to store the above mentioned data.
The accumulation function to totalize these mass values and to count the number
of accumulations.
The hold function enables weighing a living animal.
UFC (Universal Flexi Coms) function to customize the protocol of outputting data
using the serial interface.
The following interfaces are either standard or are available as an option:
The RS-232C serial interface to communicate with a computer, printer or remote
display. This interface outputs data and can request weight data, enter
parameters and control the state of the indicator. (Options: OP-04, OP-05, OP-08)
RS-422/485, 3-Relay Outputs (Option: OP-03)
RS-232C, 3-Relay Outputs and 3-Control Inputs (Option: OP-05)
Analog Output (4-20 mA) (Option: OP-07)
RS-232C, Current Loop Output, 3-Relay Outputs and 1-Control Input (Option: OP-08)
Only one interface can be installed at a time.
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
