7.4.1 Viewing a Spectrum Chart
Click on the button to view a spectrum chart for the selected channel. To change a channel, click on
the window with the right mouse button, select Channels..., check the channel you want displayed, and
then click OK. PAS provides voltage, current, active power and reactive power spectrum charts.
PAS can give you indication on whether harmonic levels in the sampled waveforms exceed compliance
limits defined by the power quality standards or local regulations.
To review or change harmonic limits:
1. Click on the spectrum window with the right mouse button and select Limits….
2. Select a known harmonics standard, or select Custom and specify your own harmonic limits.
3. 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.
