Indicator
Total display area
0.15 to 130% of selected range (RMS voltage and current; ef-
fective, apparent and reactive power; power factor)
Display is suppressed to zero when less than 0.15%.
0.3 to 130% of selected range (DC voltage)
Display is suppressed to zero when less than 0.3%.
0 to 130% of selected range (measurement items other than
the above)
Effective measurement
area
1 to 110% of selected range
Miscellaneous Measurement Items
(for all calculation items, there are no gaps of measurements)
RMS Voltage
Measurement method
True RMS method
Waveform consists of 256 points/cycle, measured every 12 or
10 cycles at 50 or 60 Hz, respectively (approx. 200 ms)
Waveform consists of 256 points/8cycles, measured every 80
cycles at 400 Hz (approx. 200 ms)
Display conversion
function
Three-phase 3-wire (3P3W3M):∆ (line-to-line voltage) - Y
(phase-to-neutral voltage) conversion (center point calculated
by weighting)
Three-phase 4-wire: Y (phase-to-neutral voltage) - ∆ (line-to-
line voltage) conversion
Range selection
Manual ranging (range for channels 1 to 3 selected in the same
operation)
DC measurement
