Instrument Transformer Correction (ITC) allows you to correct for inaccuracies in the current transformers (CTs) and potential transformers (PTs).

The ITC feature is not available with PowerLogic PM5000 series meter's.

ION7550/ION7650 meters are shipped with ITC-capable firmware, its ITC modules (Instr Xformer in the firmware) must be configured using accurate

measurements to ensure valid calculations. There is one Instr Xformer Correction module for each current and voltage input into the meter.
