This screen (Fig. 202) displays the harmonic values and the THD% value of voltage V31
and current I3 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.

The following keys are active on this page:
 The up (ZOOM+) or down (ZOOM-) arrow keys zoom in or out the histogram.
 The left and right arrow keys move the cursor left/right along the harmonics.
 The F1 key (or the PAG item on the display) advances to the following page of saved
values, relative to phase 3 harmonics.
 The F2 key (or the ARM V or ARM I item on the dislay) switches between voltage and
current harmonics relative to Phase 1.
 The F4 key (or the ARM PAG item on the display) displays the following harmonics
group. 0..9, 10..19, 20..29, 30..39, 40..49.
 The ESC key (or the smart icon on the display) to exit the function and go back to the
“Recording analysis” page (Fig. 181).
This screen (Fig. 203) displays the harmonic values and the THD% value of neutral
voltage Vn and 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.

The following keys are active on this page:
 The up (ZOOM+) or down (ZOOM-) arrow keys zoom in or out the histogram.
 The left and right arrow keys move the cursor left/right along the harmonics.
 The F1 key (or the PAG item on the display) advances to the following page of saved
values relative to total harmonics.
 The F2 key (or the ARM V or ARM I item on the dislay) switches between voltage and
current harmonics relative to Phase 3.
 The F4 key (or the ARM PAG item on the display) displays the following harmonics
group. 0..9, 10..19, 20..29, 30..39, 40..49.
 The ESC key (or the smart icon on the display) to exit the function and go back to the
“Recording analysis” page (Fig. 181).
