Calibrate the ControlLogix Isolated Analog
I/O Modules
The ControlLogix isolated analog I/O modules are calibrated during the
manufacturing process. Each module’s accuracy remains high throughout its
lifespan.
You must add the module to your Logix Designer application project, as
described in Chapter 7
, before you can calibrate it.
You calibrate isolated analog I/O modules on a channel-by-channel basis or with
the channels grouped together.
If you choose to calibrate your module, we recommend the following:
Calibrate all channels on your module each time you calibrate.
This maintains consistent calibration readings and improve module
accuracy.
Use an extra 1756-TBCH RTB to calibrate your module.

IMPORTANT
You are not required to calibrate the module at any point in its lifespan.
This chapter describes the tasks associated with module calibration if you
choose to calibrate the module at any point in their lifespan.
