2-16 9700 POWER METER USER’S GUIDE
Power Quality Monitoring Framework

This portion of the factory configuration monitors the phase voltage

signals for sag/swell and transient events, and triggers waveform

recordings when they occur (statistics are also recorded for each event). A

trigger is provided for manual waveform recording, and counters are

included to display the number of events that have occu rred (an additional

trigger provided to reset these counters).
