5.7.3.2. Graph
This screen (Fig. 145) contemporarily shows the saved instant values of the waveforms of
voltages V1, V2, V3, Vn scaled according to the Full scale (Fs) and the relevant RMS
values; these values have been saved by the instrument upon pressing the
SAVE
key.
As an example, below are shown the screens relative to a
three phase 4-wire system
. Similar
consideration can be applied to any other selected system.

The following keys are active on this page:
The up (
ZOOM+
) or down (
ZOOM-
) arrow keys zoom in or out the displayed
waveforms
The
F1
key (or the
PAG
item on the display) advances to the following page of saved
current values
The
ESC
key (or the smart icon on the display) to exit the function and go back to the
“Recording analysis” page (Fig. 143)
5.7.3.3. Harmonics
analysis
This screen (Fig. 146) displays the harmonic values and the THD% value of voltages V1, V2,
V3, Vn and of currents I1, I2, I3 and of Neutral current In in a graph (scaled according to the Full
scale Fs) or in a table. The values displayed are percentage values of the fundamental or
absolute values according to the configuration set in the
ANALYZER CONFIGURATION
MENU -> ADVANCED
. As an example, below are shown the screens relative to a
three phase
4-wire system
. Similar consideration can be applied to any other selected system
Fig. 146: Total harmonics in three-phase 4-wire system
Should only the voltage signals or only the current signals be connected to the
instrument’s inputs, all displayed harmonics will be shown in the upper half plane of the
graph. If both voltage and current signals are connected to the instrument’s inputs, the
histogram bars representing the harmonics will be shown respectively:
