2. Control area
•
When the pointer is placed on one of a channel's parameters, it
directly opens the associated "Sensitivity/Coupling" and "Vertical
Scale"
menus.
•
The pointer validates the channels.
•
The "
"
symbol indicates whether the channel is selected.
3. Status area
The status area indicates the automatic measurements performed on the
signals and the selected harmonic.
The "SIGNAL" area
This indicates:
-
the active channel(s):
ch1
to
ch4
, (- - -) when the channel is not
active
-
the RMS voltage of the signal in V
-
the harmonic distortion rate (THD) in %

=
The "Ref.:
Fundamental »
or "Harmonic X" area
This indicates, for the fundamental or the selected harmonic, (
Example:
Ref. Harmonic 3
):
-
its value as a % of the harmonic of the strongest amplitude
-
its phase in ° in relation to the fundamental
-
its frequency in Hz
-
its RMS voltage in V
4. Menu bar
The same menu toolbar is used as in "Oscilloscope" mode; some menus
are adapted to the "Harmonic Analysis" mode and the others are not active.
Display of information
on the traces
Display of information on the
fundamental or the harmonic
selected
Using the stylus, display of:
the parameters of the traces in the
same color as the trace: validity,
coupling, bandwidth limit,
sensitivity
