HVREX_a019_ShuntTcrCalNotUsed

The shunt thermal coefficient of resistance (TCR) calibrations are not being used for high voltage (HV) current sensing. The default shunt TCR coefficients will be used and current measurement accuracy may be reduced.

Impact

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

Description

The shunt thermal coefficient of resistance (TCR) calibrations are not being used for high voltage (HV) current sensing. The default shunt TCR coefficients will be used and current measurement accuracy may be reduced.

Cause

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.
