Readout Description
rms V AC Voltage AC value on channel A
THD %f
THD is the amount of harmonics in a signal as a percentage
of the total RMS value (THD%r) or as a percentage of the
fundamental (THD%f). It is a measure of the degree to which
a waveform deviates from a purely sinusoidal form. 0%
indicates that there is no distortion. You can select THD%r or
THD%f in the Settings menu (3).
Nr (3)
The harmonics component as selected with the cursor. Use
WX to move the cursor. In the example screen this is the third
harmonic. The values to the right of this number will change
when the cursor is moved to another harmonic component.
V Voltage of the harmonic component as selected by the cursor.
%f
The amount of the selected harmonic component in the
voltage signal as a percentage of the total RMS value
(THD%r) or as a percentage of the fundamental (THD%f). You
can select %r or %f in the Settings menu (3).
Deg
The phase angle between the harmonic component and the
fundamental voltage.
