5.3 Waveform Mode
This mode displays the current and voltage curves, along with the values mea-
sured and those calculated from the voltages and currents (except for power,
energy and harmonics).
Item
Measurement Type
RMS
Measurement of the true RMS value
THD
Measurement of total harmonic distortion
CF
Measurement of the peak factor
Display of min/max RMS and peak values (see § 5.3.4)
Simultaneous display of voltage and current measurements (see § 5.3.5)
Display of Fresnel diagram of signals (see § 5.3.6)
5.3.1 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 § 4.3.4).
