Display range Same as r.m.s. voltage
Crest factor Same as r.m.s. voltage
Input impedance Same as r.m.s. voltage
Threshold value Percentage of the nominal voltage value
Meas. system Complied with IEC61000-4-3
*r.m.s. values are calculated from one waveform with half-wave overlapping.
Swell, dip detection for multi-phase system:
Starts when any one of events starts at any ch, Ends when it terminates.
INT detection for multi-phase system:
Starts when the event starts at all chs, Ends when it terminates at any one of
the chs.
Accuracy 10% - 150% (to 100V or higher nominal voltages) : nominal voltage ±1.0%
Out of above range : ±0.4%rdg±0.4%f.s.
Errors of event duration measurement at 40 - 70Hz : within 1-cycle
