waveforms exceed compliance limits defined by the power quality standards or local
regulations.
To review or change harmonic limits:
Click on the spectrum window with the right mouse button and select “Limits…”.
Select a harmonics standard, or select “Custom” and specify your own harmonic limits.
Check the Enabled box to visualize harmonic faults on the spectrum graph and in harmonic
tables.
Harmonics that exceed selected compliance levels are colored in red on the graph and in
the tables.
