This screen (Fig. 142) displays the harmonic values and the THD% value of voltage V2
and current I2 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 right and left arrow keys move the cursor to the right or to the left 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 2.

 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
