Module Calibration
In this chapter we tell you how to calibrate your module.
To calibrate your analog module, you will need the following tools and
equipment:
Tool or Equipment Description
Precision Voltage Source 0-10V, 1
µ
V resolution
Precision Multimeter
25mA, 1 µ A resolution
10V, 1 µ V resolution
Programming Terminal
and Interconnect Cable
Programming terminal for A-B family processors
Your analog module is shipped already calibrated from the factory. To
recalibrate the module, it must be able to communicate with the processor
and a programming terminal.
If the processor has block transfer capability, you must enter ladder logic
into the processor memory before calibrating the module. You can then
initiate BTWs to the module, and the processor can read inputs from the
module (BTRs).
