Initially, there must be one or two traces on channels CH1 to CH4.
Recall
-
Only the channels (and not the functions) can be the subject of
harmonic analysis.
- In this mode, the time base is not adjustable.

The "SIGNAL" table under the breakdown provides information on:
-
the active channel(s) (CH1 to CH4)
- the RMS voltage of the signal in V
-
harmonic distortion rate (in %) of the signal

The " " symbol, present on the fundamental (F) or one of the
harmonics and modifiable using the stylus, means that measurements
can be made on the harmonic selected.
