The total current-voltage harmonic values are displayed in THD V% and THD I% menus as graphic bars
on the left. Any time at the instantaneous values menu (except THD V% and THD I%), you can scroll between
THD V and THD I with pressing ESC button. Harmonic menu can be used for watching the harmonic values
detailed.
NOTES:
*
If there is “-” symbol before the measured active power, it indicates the existence of active export power.
