Event “ Over ” / ” Under ” event
2
selectable based on the threshold value for each channel
1. Full Scale (FS) indicates 50 V.
2. An “ Over ” event indicates an event where the measured value rises above the threshold. An “ Under ” event
indicates an event where the measured value falls below the threshold. Over and Under voltage events consist of
start and end events. Either event can be configured.
