Calibrate the ControlLogix Analog I/O Modules Chapter 11
A Results wizard displays the status of each channel after calibrating for
a low reference. If channels are OK, continue. If any channel reports an
error, retry
step 10 until the status is OK.
11. Set the calibrator for the high reference voltage and apply it to
the module.
The High Reference Voltage Signals wizard appears to show which
channels will be calibrated for a high reference and the range of the
calibration. It also shows what reference signal is expected at the input.
