8.5.3. "HARM" mode

Selecting the HARM mode the screen below will be displayed according to the settings
made as per paragraph 8.1. The screen shows the harmonics (see paragraph 16.6) of the
current.
The symbols used are described in Tab. 2.
For eventual messages displayed see appendix 1 – MESSAGES DISPLAYED.
The displayed histograms represent the harmonic content of the current under test. The
value of the first harmonic h01 (primary at 50Hz) is not represented in scale along with the
other harmonics in order to maximise the display of the latter. In case both voltage and
current are connected to the instrument inputs, eventual negative values (therefore
represented under the horizontal axis), indicate that such current harmonics are
"generated" by the load.
Following keys are enabled:
