These screenshots show the instrument in Harmonic Analyzer mode with a square
wave input. Comparisons can be made of Current, Power, Voltage and Total
Harmonic Distortion on all 3 phases. When looking at a single channel it is also
possible to check the frequency of the signal. The final screenshot shows that it is
also possible to look at the harmonics in table form so that it is possible to look at
all of the individual harmonics at once. This example was for the voltage harmonics
but it is also possible to get the same table format for current harmonics.
We have used a square wave as the harmonics of this waveform are well known, it
is advisable to compare the harmonic values in the displayed table and ensure they
are nominally the same as the table below;
