PQ Recorder Setup
The PQ recorder setup allows you to adjust thresholds and
hysteresis for PQ triggers, to define the waveform log options
for PQ events, and to enable or disable the PQ recorder in
your device.
To configure the PQ recorder:
1. Select Memory/Log from the Meter
Setup menu, and then click on the PQ
Recorder tab.
2. Adjust thresholds and hysteresis for
PQ triggers if required.
3. Select the waveform logging options
for PQ events.
