Inter-harmonics
When active power (P) is selected as the display item, inter-harmonics
are not displayed.
The setting can also be changed without using the pull-down menu by

d the right inter-harmonics.
The inter-harmonics order is obtained by add-
ing 0.5 to the harmonics order for the same
ro
w.
Example:
The order of inter-harmonics on the right of
the
20th harmonic is 20.5.
