corresponding to Phase A, B and C.
Single harmonic parameters: Under single phase mode, display single harmonic
distortion factor and phase of the single phase. Under three-phase mode,
display the single harmonic distortion factor and corresponding phase.
z Harmonic list screen
When LIST mode is selected in the harmonic measurement mode, the list
of harmonic measurement results will be displayed, when “U” is selected,
the list will display the voltage and phase values under various harmonics.
When “I” is selected, the current and phase values will be displayed. Under
single-phase mode, the list only displays measurement results for Phase A,
and displays 0 for the other two phases, as shown in the figure below; under
three-phase mode, display effective values for the three phases.
Harmonic number list: the signal data of 0-50
th
harmonic(s) will be shown in
the LIST. You can press the Up and Down key to display the hidden rows,
i.e. hidden data of single harmonic data.
z Introduction to vector interface
When vector mode is selected in the harmonic measurement mode, to enter
the vector measurement interface, as shown in the figure below.
