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"
manually. 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.
8. To calculate the average results over several measurements, select "Average" and
define the number of results to consider.
9. To clear the result data used for statistical evaluation and start a new measure-
ment, select "Clear Results".
To save the results to a file
1. Press the [FILE] key.
2. Select "Harmonics".
3. Check the "Harmonic Directory" and the "Filename Base". Adjust if necessary.
4. Select "Save".
For details on the format of the result file, see Chapter 6.3.6.2, "Export File Format for
Harmonic Results", on page 144.
