In this chapter we tell you what tools you need and how to calibrate your
module.
In order to calibrate your input module you will need the following tools
and equipment:

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.
Damage to the equipment or personal injury may result.
