Module Field Calibration
The module provides autocalibration, which compensates for offset and gain
drift of the A/D converter caused by a temperature change within the module.
An internal, high-precision, low drift voltage and system ground reference is used
for this purpose. The input module performs autocalibration when a channel is
initially enabled. In addition, you can program the module to perform a
calibration cycle once every 5 minutes. See
