longer waveform will be also recorded, synchronized
with the fast transient waveform.
You can temporary disable the PQ recorder in your meter.
To enable or disable the PQ recorder:
1. Check or uncheck the Recorder Enabled checkbox.
2. Send your setting to the device.
Note that disabling the PQ recorder in your meter does not
affect the evaluation and recording of the EN50160 statistics.
Indication of Power Quality Events
When the PQ recorder detects a power quality fault, it
generates the specific internal event “PQ EVENT” that can be
monitored through a control setpoint. The event is asserted
all the time while the fault condition exists. The “PQ EVENT”
trigger can be used to give a power quality fault indication via
relay contacts, or can be combined using the AND operator
with timer ticks for periodic data recording at the time of the
fault to produce voltage trending charts.
