Figure 22 – Abnormal Voltage Report

Trigger Logic
The triggering logic uses a low and high threshold, a nominal
voltage, and a trigger duration. The thresholds are added and
subtracted to the nominal voltage to find triggering points. If the
voltage crosses a triggering point for longer than the trigger
duration, an abnormal voltage event occurs.
