Viewing a Spectrum Table
Click on the button on the local toolbar. The spectrum table displays voltage, current,
active power and reactive power harmonic components both in percent of the fundamental
and in natural units, and phase angles between the harmonic voltage and current.
To change a phase, click on the window with the right mouse button, select “Options...”,
check the phase you want displayed, and then click OK.
Viewing a Frequency Plot
Click on the button to view a cycle-by-cycle voltage frequency plot.
Viewing Synchronized Waveforms Viewing Synchronized Waveforms Viewing Synchronized Waveforms Viewing Synchronized Waveforms
If you have a number of devices with synchronized clocks, you can view waveforms
recorded at different locations in one window. Power Software synchronizes the time axes
for different waveforms so they could be displayed in a single plot.
To get synchronized waveforms:
Put the databases with waveforms into the same folder, or put the sites from which you
have uploaded data to the same group in the sites tree.
Open a waveform you want to synchronize with other waveforms, and then click on the
Multi-site View button . Power Software searches for time-coordinated waveforms that
have the same time span as the selected waveform.
