Measurement method Calculates the average by dividing the active power integrated value by the integration
time.
Measurement accuracy (Active power measurement accuracy) + (±0.01% rdg. ±1 dgt.)
Effective measuring range As per the active power integration effective measurement range.
Display range ±0% to ±3,745.4% of the range (no [o.r] display)
Polarity Yes
Peak exceeded warning If the integrated value includes data from when the PEAK OVER U or PEAK OVER I
lamp lit up, the unit W will flash.
Invalid data display Displays [- - - - -] when using the AC or FND rectifier.
Display types When the TOTAL lamp is lit up
In auto-range integration mode, the time-average value for the overall range is dis-
played.
When the TOTAL lamp is turned off, or when using fixed-range integration mode
The time-average value for the range being shown is displayed.
Measurement method Calculates the AC component (peak to peak [peak width]) as a proportion of the voltage
DC component.
Effective measuring range As per voltage and voltage waveform peak value effective measurement ranges.
Display range 0.00 to 500.00
Polarity None
Over-range display Displays [o.r] when [o.r] is displayed for the voltage waveform peak value.
Displays [o.r] when [o.r] is displayed for the voltage or the voltage is 0.
Measurement method Calculates the AC component (peak to peak [peak width]) as a proportion of the current
DC component.
Effective measuring range As per current and current waveform peak value effective measurement ranges.
Display range 0.00 to 500.00
Polarity None
Over-range display Displays [o.r] when [o.r] is displayed for the current waveform peak value.
Displays [o.r] when [o.r] is displayed for the current or the current is 0.
Measurement method Calculates the ratio of the current crest factor to the power factor.
Effective measuring range As per power factor (voltage, current, active power) and current crest factor (current,
current waveform peak value) effective measurement ranges.
Display range 1.0000 to 6.1200 M
Polarity None
Over-range display Displays [o.r] (MCR > 10) when [0.0000] is displayed for the power factor.
Displays [o.r] (MCR > 10) when [o.r] is displayed for the current crest factor.
