on working with tables.
Viewing Real-time Harmonic Spectrum
To retrieve real-time harmonic spectrum from your meter:
1. Check the On-line button
on the Power Software
toolbar.
2. Select the device site from the list box on the toolbar.
3. Select RT Harmonic Monitor from the Monitor menu.
Use the Poll button
for a single-step poll or the
Continuous poll
button for continuous polling. To stop
continuous polling, click on the Stop button .
Viewing Synthesized Waveforms
To view synthesized waveforms of voltages and currents,
click on the button on the local toolbar.
See Viewing Waveforms in Chapter 9 for information on using
different spectrum views.
Viewing Real-time Waveforms
To retrieve real-time waveforms from your meter:
1. Check the On-line button
on the Power Software
toolbar.
2. Select the device site from the list box on the toolbar.
3. Select RT Waveform Monitor from the Monitor menu.
Use the Poll button
for a single-step poll or the
Continuous poll
button for continuous polling. To stop
continuous polling, click on the Stop button .
Power Software normally retrieves seven 4-cycle AC
waveforms (V1-V3 and I1-I4) sampled at a rate of 128
samples per cycle. If you wish to get only selected phases,
select “Options” from the Tools menu, click on the
Preferences tab, check the phases you want polled, and then
click OK.
Retrieved waveforms can be displayed in different views as
overlapped or non-overlapped waveforms, as an RMS cycle-
by-cycle plot, or as a harmonic spectrum chart or a table.
See Viewing Waveforms in Chapter 9 for information on using
different waveform views.
