HVREX_a017 — Shunt Asic Cal Not Used

Full alert identifier: HVREX_a017_ShuntAsicCalNotUsed

Alert description

The programmed shunt application-specific integrated circuit (ASIC) calibration is not being used for high voltage (HV) current sensing. The default shunt ASIC gain will be used and current measurement accuracy may be reduced.

Potential impact

The default shunt ASIC gain will be used for high voltage (HV) current sensing. Shunt current measurement accuracy may be reduced.

Set condition

The stored shunt ASIC gain is invalid or the written gain is outside the allowed tolerance.

Clear condition

The stored shunt ASIC gain is valid and the written gain is within the allowed tolerance.
