5.3 Measurement specifications
143
Phase Angle Measurement Specifications (φ: Displayed as ° on panel display)
Frequency Measurement Specifications
(f: Displayed as V Hz or A Hz on panel display)
Integration Measurement Specifications
Measurement types Rectifiers: AC, FND
Effective measuring range As per voltage, current, and active power effective measurement ranges
Display range +180.00 to -180.00
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 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 power factor.
Invalid data display Displays [- - - - -] when using the AC+DC, AC+DC Umn, or DC rectifier.
Number of measurement
channels
6
Measurement method Calculated from input waveform period (reciprocal method)
Measurement ranges 100 Hz/ 500 Hz/ 5 kHz/ 200 kHz (linked to zero-cross filter)
(The measurement ranges of 100 Hz and 5 kHz will be added to the firmware with the
version number 1.10)
Measurement accuracy ±0.1% rdg. ±1 dgt. (0°C to 40°C)
Effective measuring range 0.1 Hz to 100 kHz
For sine wave input that is at least 20% of the measurement source’s measurement
range
Measurement lower limit frequency setting: 0.1 sec. / 1 sec. / 10 sec. (linked to synchro-
nization timeout setting)
Display format 0.1000 Hz to 9.9999 Hz, 9.900 Hz to 99.999 Hz, 99.00 Hz to 999.99 Hz,
0.9900 kHz to 9.9999 kHz, 9.900 kHz to 99.999 kHz, 99.00 kHz to 220.00 kHz
Over-range display Displays [o.r] when input falls outside the measurement range.
Invalid data display Displays [- - - - -] when using the DC rectifier.
Measurement items Simultaneous integration of the following 6 parameters for each channel (total of 18 pa-
rameters):
Sum of current integrated values (displayed as Ah on panel display)
Positive current integrated value (displayed as Ah+ on panel display)
Negative current integrated value (displayed as Ah- on panel display)
Sum of active power integrated values (displayed as Wh on panel display)
Positive active power integrated value (displayed as Wh+ on panel display)
Negative active power integrated value (displayed as Wh- on panel display)
