The Waveform
button displays current and voltage graphs, along with the values measured and those calculated from the
voltages and currents (except for power, energy, and harmonics).
This is the first display screen that appears when the instrument is powered ON.
Maximum and minimum RMS
values and peak values (§7.4).
Peak factor (§7.3).
Total harmonic distortion (§7.2).
True RMS value (§7.1).
7.1. TRUE RMS
The RMS sub-menu displays the waveforms over one period of the signals measured and the true RMS voltage and current.
The choice of graphs to display depends on the type of connection (see §4.6):
■
Single-phase, 2-wire or Split-phase, 2-wire: no choice (L1)
■
Single-phase, 3-wire:
RMS, THD, CF,
•
: no choice (L1)
•
■
Split-phase, 3-wire:
RMS, THD, CF,
•
: 2V, 2A, L1, L2
•
■
Split-phase, 4-wire:
RMS, THD, CF,
•
•
: 2V, 2A, L1, L2
■
Three-phase, 3wire: 3U, 3A
■
Three-phase, 4-wire: 3U, 3V, 3A, L1, L2, L3
■
Three-phase, 5-wire:
RMS, THD, CF,
•

: 3U, 3V, 3A, L1, L2 and L3
The following examples were obtained with a three-phase 5-wire connection.
