Measurement method Measures the current waveform’s peak value (for both positive and negative polarity)
based on sampled instantaneous current values.
Range configuration
Measurement accuracy ±2.0%f.s. at DC and when 10 Hz f 1 kHz (f.s.: current peak range).
Provided as reference value when 0.1 Hz f < 10 Hz and when 1 kHz < f.
The above measurement accuracy is multiplied by 2 for the 1 mA range.
Effective measuring range ±5% to ±100% of current peak range, however, up to ±60 A
Display range Up to ±102% of current peak range, however, the value 0 will be displayed if the current
RMS value triggers the instrument's zero suppression function.
Over-range display Displays [o.r] when input exceeds ±102% of the current peak range.
Default state Current peak range: 120 A
Current range 1 mA 2 mA 5 mA 10 mA 20 mA 50 mA 100 mA
Current peak range 6.0000 mA 12.000 mA 30.000 mA 60.000 mA 120.00 mA 300.00 mA 600.00 mA
Current range 200 mA 500 mA 1 A 2 A 5 A 10 A 20 A
Current peak range 1.2000 A 3.0000 A 6.0000 A 12.000 A 30.000 A 60.000 A 120.00 A
Measurement method Calculates the ratio of the voltage waveform peak value to the voltage RMS value.
Effective measuring range As per voltage and voltage waveform peak value effective measurement ranges.
Display range 1.0000 to 612.00 (no polarity)
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 ratio of the current waveform peak value to the current RMS value.
Effective measuring range As per current and current waveform peak value effective measurement ranges.
Display range 1.0000 to 612.00 (no polarity)
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 average by dividing the current integrated value by the integration time.
Measurement accuracy (Current measurement accuracy) + (±0.01% rdg. ±1 dgt.)
Effective measuring range As per the current integration effective measurement range.
Display range ±0% to ±612% of the range (no [o.r] display)
Polarity Has polarity when using the DC rectifier.
Peak exceeded warning If the integrated value includes data from when the PEAK OVER I lamp lit up, the unit
A will flash.
Invalid data display Displays [- - - - -] when using the AC or FND rectifier.
If the auto-range integration mode rectifier is AC+DC or AC+DC Umn, [- - - - -] will be
displayed.
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.
