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)
Power Factor Measurement Specifications (λ: Displayed as PF on panel display)
Measurement types Rectifiers: AC+DC, DC, AC, FND, AC+DC Umn
Effective measuring range 0% to 169% of the range
However, defined when the voltage and current fall within the effective measurement range.
Display range 0% to 196% 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 ±196% of the range.
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 196% 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 196% 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.
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 ±0.0000 to ±1.0000
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 or current, or when the displayed ap-
parent power is 0.
Invalid data display Displays [- - - - -] when using the DC rectifier.
