The analog input module is shipped from the factory already calibrated.
If necessary to recalibrate the module, you must calibrate the module in an
I/O chassis. The module must communicate with the processor and
industrial terminal. Calibration consists of adjusting the 10V reference and
nulling the input offset.

Important: The module must be powered up for at least 30 minutes before
attempting to calibrate.

ATTENTION: Do not attempt to calibrate your module until
you have read and thoroughly understand this procedure. Also,
do not attempt to calibrate this module in an operating system.
