1-10 Overview
Module Field Calibration
The 1769-IF4 and -IF8 input modules performs autocalibration when a
channel is initially enabled. In addition, if a channel is configured differently
than the previously scanned channel, an autocalibration cycle is run as part of
the reconfiguration process.
The 1769-OF2, -OF8C, and -OF8V output modules’s calibration is
guaranteed by its design. No field calibration is required.
