The Calibration Module (CM) provides the proper AC excitation voltage to the DCCT and provides a calibration
adjustment to obtain a proper field amperes reading. This calibration is performed with a potentiometer.
The Calibration Module is required to utilize field current and/or field overtemperature features. It is included in
the optional PG2SPM or PG4SPM accessory packages.
