Threshold
Specify as a percentage of the nominal voltage.
Measurement system
Complies with IEC61000-4-30
The rms value is calculated on a single waveform that
overlaps every half a waveform.
Multi-phase system swell, dip judgment condition:
The start of an event is assumed when any of the
channel starts an event, and the end of the event is
assumed when all the channels finished their events.
Multi-phase system interruption judgment condition:
The start of an event is assumed when all that
channels start their events, and the end of the event is
assumed when any of the channel finishes its event.
Accuracy
10% to 150% for nominal voltage 100 V or higher:
nominal voltage±1.0%
Outside the above range: ±0.4%rdg±0.4% rng
Measurement error in the event persistence time in the
frequency range of 40 to 70 Hz: within 1 cycle
