Measurement method
Vrms, Arms 10/12 2 cycle contiguous non overlapping intervals using 500/416 2 samples per cycle in
accordance with IEC 61000-4-30
Vpeak, Apeak Absolute highest sample value within 10/12 2 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
Vrms 1 ⁄

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

VA Selectable Total or Fundamental apparent power display
Calculates apparent power using Vrms x Arms value over 10/12 cycle period
Total Apparent Power is root mean square of real and apparent power
VAR Selectable Total of Fundamental reactive power display
Calculates reactive power as root of VA squared minus Watt squared over 10/12 cycle period
Capacitive and inductive load is indicated with capacitor and inductor icons
Power Factor Calculated Watt / VA
Cos ϕ / DPF Cos of angle between fundamental voltage and current
Unbalance The supply voltage unbalance is evaluated using the method of symmetrical components
according to IEC61000-4-30
Flicker According to IEC 61000-4-15 Flickermeter - Functional and design specification
Includes 230 V 50 Hz lamp and 120 V 60 Hz lamp models
Transient capture Captures waveform triggered on signal envelope
Additionally triggers on dips, swells, interruptions and Amps level as specified by IEC61000-4-30
Inrush current The inrush current begins when the Arms half cycle rises above the inrush threshold, and ends
when the Arms half cycle rms is equal to or below the inrush threshold minus a user-selected
hysteresis value. The measurement is the square root of the mean of the squared Arms half
cycle values measured during the inrush duration. Each half-cycle interval is contiguous and
non-overlapping as recommended by IEC 61000-4-30. Markers indicate inrush duration.
Cursors allow measurement of peak Arms half cycle.
