alert tolerance

Indicates a reading that is acceptable, but is closer to the device tolerance limits than desired. Alert tolerances fall within device tolerance limits and are always calculated as a percentage value.

The lower and upper alert tolerances are calculated based on the following equations:

Lower Work Order Alert Tolerance = Standard - [(Alert Tolerance / 100) * (Standard - Lower Equipment Device Tolerance)]

Upper Work Order Alert Tolerance = Standard + [Alert Tolerance / 100) * (Upper Equipment Device Tolerance - Standard)]
