7.8.2.2.1 Global values
Irms, I1 and THDI are displayed in table format.
7.8.2.2.2Waveforms
The line current waveforms for all phases (3-W mode) and the neutral current waveform
(4-W mode). The graph layout is similar to the one of the voltages (
). All
waveforms are synchronized with the rising edge zero crossing of the voltage V (L1-N)
(4-W mode) or V (L1-L2) (3-W mode).
7.8.2.2.3Spectrum
The line current spectrum for all phases (3-W mode) and the neutral current spectrum (4-
W mode) in chart format. The chart layout is similar to the one of the voltages (
).
7.8.2.2.4Harmonic table
The line current spectrum for all phases (3-W mode) and the neutral current spectrum (4-
W mode) in table format. The table layout is similar to the one of the voltages
