This holds the major-high alarm threshold configured for the Offset Control parameter, expressed in the unit given by uomOffsetNomCnt (typically dB). If currentValueOffsetNomCnt rises above this threshold, the module raises a majorHighAlarm condition reflected in alarmStateOffsetNomCnt, the most severe high-side warning for this parameter. An admin sets this threshold based on the module's known safe operating range for the adjustable counterpart to the Offset Monitor reading, letting an operator nudge that internal offset back toward nominal.
