Functional Description

4.5.3. Icons/screen in Harmonic mode
Display of the result of the harmonic
analysis of the selected traces.
The harmonic analysis of traces
ch1 and ch4 is represented in the form of
solid-colour bar charts
(in the colour of the trace).
As default, the fundamental is selected
automatically, but the fundamental
frequencies of 50Hz/60Hz and 400Hz
can be programmed manually.
The measurement parameters displayed:
Measurement on the signal
- the RMS voltage of the signal in V
- the total harmonic distortion (THD) in %,
per standard EN50160
Measurement on a harmonic
- the value in %, ratio
- the phase in ° with respect to the
fundamental
- its frequency in Hz
- its RMS voltage in V
 Example: Harmonic of order 1, incrementing of display of the
harmonic order by + and decrementing by -
Measurement of power harmonics
