(5) Attention: The absolute value of the offset must not exceed 95% of the peak amplitude. In other words, s(t) = S ×
sin(ωt) + O, so |O| ≤ 0.95 × S (S positive). The 'half-period' values are the MAX and MIN values of the waveforms mode and
the V and A values used in the Alarm mode and the Inrush mode.
RMS RMS
(6) For the phase-to-earth voltage measurement (phase-neutral). For the phase-to-phase voltage measurement (phase-phase), in
balanced three-phase mode, it is possible to reach 660V
V ).
RMS
NOTE: Accuracy given for power and energy measurements are maximum for Cos φ = 1 or Sin φ = 1 and are typical for the other
phase shifts.
