5.3.3 Performing a Harmonic Measurement
1. Select the "Harmonic" mode.
2. To adjust the instrument settings to the current input signal automatically, press
AUTOSET.
The AUTOSET function detects the fundamental frequency in the signal automati-
cally if it lies between 10 Hz and 1 kHz. If none of the predefined values (50 Hz,
60 Hz, 400 Hz) fit, a "User" value is set.
3. Alternatively to the AUTOSET function, define the "Fundamental Frequency" man-
ually. Select "User" and enter the frequency.
4. If a "Clipping" message is displayed next to the channel indicator in the numeric
result area of the screen, the signal is not entirely within the defined measurement
range. Use the AUTOSET key or the RANGE keys to correct the range.
5. To perform a limit check, do one of the following for the "Limits" setting:
● To check the limits specified by the standard, select "EN50160".
● To configure user-specified limits in a file, select "User" and open the .csv file.
6. To restrict the number of harmonics to be displayed in the bargraph, use the "Dis-
play Selection" setting.
Select a predefined selection, or define the number in the "Max No Harmonics"
field.
7. To display the results for a specific harmonic, select the number below the bar in
the graph.
