13.3 Measurement Specifications
188
Specified for RMS voltage Urms and RMS current Irms. Current and power values incorporate clamp sensor accuracy.
V10 Flicker (dV10)
Measurement method "13.10 Calculation Formula" (p.198)
Calculated values are subject to 100 V conversion following gap-less measurement once each minute.
Standard voltage Automatic (with AGC)
Displayed item V10 measured at one minute intervals, average value for one hour, maximum value for one hour,
fourth largest value for one hour, total (within the measurement interval) maximum value
Measurement range, resolution 0.000 to 99.999 V
Measurement accuracy 2% rdg.0.01 V (with a fundamental wave of 100 Vrms [50/60 Hz], a fluctuation voltage of 1 Vrms,
and a fluctuation frequency of 10 Hz)
Threshold 0.00 to 9.99V Alarm output is generated when the reading for each minute is compared to the
threshold and found to be greater
Event IN N/A
Event OUT N/A
Multiple-phase system treatment None
IEC Flicker (Pst, Plt)
Measurement method Uses IEC61000-4-15:1997 +A1:2003 Ed1/Ed2, Calculated as described in "13.10 Calculation For-
mula" (p.198).
Pst is calculated after 10 minutes of continuous measurement and Plt after 2 hours of continuous
measurement.
Displayed item Short interval flicker Pst, long interval flicker Plt
Measurement range, resolution 0.0001 to 10000 PU broken into 1,024 segments with a logarithm
Flicker filter Select 230 V lamp Ed1, 120 V lamp Ed1, 230 V lamp Ed2, or 120 V lamp Ed2.
Measurement accuracy Pst 5% rdg. (Specified within range 0.1000 to 20.000 using IEC61000-4-15 Ed1.1 and IEC61000-
4-15 Ed2 Class F1 performance test.)
