5.3.2.4. Zoom with respect to the 1st harmonic option
This option permits to show harmonics graphics with a zoom relative to the first harmonic
order (fundamental) or with a zoom relative to the highest amplitude harmonic inside the
Real Time values section. Also in this case the aim is to better the final resolution of
graphics.
1. Move the cursor using arrows keys on field relative to “
Zoom 1st harm
” , marked it
with blue background.
2. Use
F3
or
F4
keys (alternatively touch
MOD(+)
o
MOD(-)
) to select one of below
options:
YES
: The meter performs the graphics zoom respect to the first harmonic
NO
: The meter performs the graphics zoom respect to the highest amplitude
harmonics except for the first harmonic. This option is active only if the zoom
graphic option (see 5.3.2.1) is set on AUTO mode
3. Press
SAVE
or
ENTER
keys (or the smart icon
) to save the selected option and
