(10) Operating status
Indicates the status of the harmonic measurement ("Hold"/"Run").
(11) Error indicator
If an error occurs during the measurement, an indicator is displayed above the bar-
graph. These indicators remain visible thoughout the measurement, for all acquisitions.
In addition, the long form of the error is indicated, blinking, for the duration of the acqui-
sition in which an error occurs only.
The following errors may be indicated:
●
"C" (Clipping)
The amplitudes determined for each frequency must be within the currently defined
amplitude range in order to be measured correctly. If the signal is not entirely within
the defined range, a "Clipping" message is displayed next to the channel indicator
in the numeric result area of the screen. The measurement is invalid and no results
are calculated.
To change the amplitude range, use the [RANGE] keys or the [AUTOSET] function.
●
"F" (Frequency)
If the specified fundamental frequency ±10 % is not detected in the signal, the
measurement is invalid.
●
"L" (Limit)
If a limit check is activated and the measured value exceeds the specified limit for
a harmonic, a limit violation has occurred. The background of the harmonic is high-
lighted red.

harmonics and the fundamental frequency.

(13) Total harmonic distortion (THD)
THD (total harmonic distortion), that is: the root mean square (RMS) amplitude (voltage
or current) of the harmonics.
The value is provided either:
