Calibrating Voltage Inputs
Use the procedure below to calibrate the voltage inputs on your analog
block I/O module. The procedure can be used for either PLC or SLC
systems.
You can calibrate any single input or output individually or, you can
calibrate them simultaneously.
Important: To allow the module to stabilize, energize the module for at
least 30 minutes before calibrating.
To calibrate your module:
1. Connect your test equipment for the input you want to calibrate. This
is shown in the figure below.
