HVREX_a018 — Shunt Bar Cal Not Used
Full alert identifier: HVREX_a018_ShuntBarCalNotUsed
Alert description
The programmed shunt bar resistance calibration is not being used for high voltage (HV) current sensing. The default shunt bar resistance will be used and current measurement accuracy may be reduced.
Potential impact
The default shunt bar resistance will be used for high voltage (HV) current sensing. Shunt current measurement accuracy may be reduced.
Set condition
The stored shunt bar resistance is invalid or the written gain is outside the allowed tolerance.
Clear condition
The stored shunt bar resistance is valid and the written gain is within the allowed tolerance.
