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 |
