Measurement method

Vrms, Arms

10/12 cycle contiguous non overlapping intervals using 500/416 samples per cycle in accordance with IEC 61000-4-30

Vpeak, Apeak

Absolute highest sample value within 10/12 cycle interval with 40 μs sample resolution

V Crest Factor

Measures ratio between the Vpeak and Vrms

A Crest Factor

Measures ratio between the Apeak and Arms

Hz

Measured every 10 sec in accordance with IEC61000-4-30

Vrms½, Arms½

Value is measured over 1 cycle, commencing at a fundamental zero crossing, and refreshed each half-cycle.

This technique is independent for each channel in accordance with IEC 61000-4-30.

Harmonics

Calculated from 10/12-cycle gapless harmonic group measurements on Voltage and Amps according to IEC 61000-4-7

Watt

Selectable Total or Fundamental real power display

Calculates average value of instantaneous power over 10/12 cycle period for each phase

Total Active Power PT = P1 + P2 + P3
