4. The screen on the side shows the values of the electric
quantities in real time. Symbols “
i
” and “
c
” respectively
indicate the inductive or capacitive nature of the load.

5. Press the
SAVE
key to store the test result in the instrument’s memory (see §
7.1
) or
the
ESC/MENU
key to exit the screen without saving and go back to the main menu.
6.
Use the arrow keys
(

)
in the
MODE
function to select
the option “
ArmV
” (voltage harmonics) or “
ArmI
” (current
harmonics). Subsequently, the instrument shows a screen
similar to the one on the side, in which the considered
amplitude of harmonics is always indicated in a
percentage
value with respect to the fundamental.
The histogram graphic of the percentage amplitudes of
the fundamental and of the voltage VL-N or current
harmonics with a
DC value up to the 25th
(the value of
the fundamental H01 is always considered equal to 100%
and is not shown) further to the value of THD% (see §
12.12) are shown on the display. The following controls
are available:
Pag
allows changing the page where harmonics are
displayed
Hxx
allows moving the cursor to increase/decrease
the harmonic order within the page
