Current Measurement Specifications (I: Displayed as A on panel display)
Active Power Measurement Specifications (P: Displayed as W on panel display)
Apparent Power Measurement Specifications (S: Displayed as VA on panel display)
Reactive Power Measurement Specifications (Q: Displayed as var on panel display)
Measurement types Rectifiers: AC+DC, DC, AC, FND, AC+DC Umn
Effective measuring range ±1% to ±150% of the range
Display range Up to ±152% of the range.
However, zero-suppression when less than ±0.5% or less than ±9 A.
Polarity Displayed when using DC rectifier
Over-range display Displays [o.r] when input exceeds ±152% of the range.
Peak exceeded warning The PEAK OVER I lamp will light up for which the input current peak value exceeds
±60 A or ±600% of the range.
Measurement types Rectifiers: AC+DC, DC, AC, FND, AC+DC Umn
Effective measuring range ±0% to ±225% of the range.
However, valid when the voltage and current fall within the effective measurement range.
Display range ±0% to ±231.04% of the range (no zero-suppression)
Polarity Positive: Power consumption (no polarity display); negative: generation or regenerated power
Over-range display Displays [o.r] when input exceeds ±231.04% of the range.
However, for 1000 V range, displays [o.r] when input exceeds ±161.196%.
Measurement types Rectifiers: AC+DC, AC, FND, AC+DC Umn
Effective measuring range As per voltage and current effective measurement ranges.
Display range 0% to 231.04% of the range (no zero-suppression)
When using the AC+DC or AC rectifier, displays S as |P| when |P| > S.
Over-range display Displays [o.r] when displaying [o.r] for either voltage or current.
Invalid data display Displays [- - - - -] when using the DC rectifier.
Measurement types Rectifiers: AC+DC, AC, FND, AC+DC Umn
Effective measuring range As per voltage, current, and active power effective measurement ranges.
Display range ±0% to ±231.04% of the range (no zero-suppression)
Polarity Polarity is assigned according to the lead/lag relationship of the voltage waveform rising
edge and the current waveform rising edge.
+: When current lags voltage (no polarity display)
-: When current leads voltage
Polarity effective range With the AC+DC, AC, or AC+DC Umn rectifier:
Sine-wave input equivalent to at least 20% of the measurement range, frequency of
10 Hz to 20 kHz, phase difference of ±(1° to 179°)
Over-range display Displays [o.r] when displaying [o.r] for the voltage, current, or active power.
Invalid data display Displays [- - - - -] when using the DC rectifier.
