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, 1µV resolution

Precision Multimeter

25mA, 1µA resolution

10V, 1

µV 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).
