parameter and use the

5.1 Waveform Mode

This mode enables the current and voltage graphs to be displayed, together with
the values measured and calculated from the voltages and currents (except for
power, energy and harmonics).
Item Measurement Type
RMS
Measurement of the true effective value
THD
Measurement of total harmonic distortion
CF
Measurement of the peak factor
Display of min, max and average values
Simultaneous display of all voltage and current measurements
Display of Fresnel diagram of signals

5.1.1 RMS Measurement

This sub-menu displays the waveforms over a period of the measured signals and
the true effective values of the voltage and the current.
The choice of graphs to be displayed depends on the type of electrical
connection that was set up during the configuration (see § 4.3).
• Single-phase: no choice (L1)
• Two-phase: 2V, 2A, L1, L2
• Tri-phase 3 or 4 wires: 3U, 3V, 3A, L1, L2, L3
• Tri-phase 5 wires:
For THD, CF and
