To retrieve waveforms, check the On-line button
on the PAS toolbar, and then
click on either the Poll button
or Continuous poll button
. Click on the Stop
button
to stop continuous polling.
PAS normally retrieves eight 4-cycle AC waveforms (V1-V4 and I1-I4) sampled at a
rate of 128 samples per cycle. If you wish to get only waveforms for selected phases,
select “Options” from the Tools menu, click on the Preferences tab, check the phases
you want polled, and then click OK.
For devices with the fast AI option (firmware V10.6.XX), PAS retrieves up to 16 AI
waveforms along with AC waveforms. To view AI waveforms, or to change channels
displayed in the window, click on the waveform window with the right mouse button,
select “Channels’, check channels you want displayed, and then click OK.
Retrieved waveforms can be displayed in different views as overlapped or non-
overlapped waveforms, as RMS cycle-by-cycle plot, or as a harmonic spectrum chart
or table. See
Viewing Waveforms in Chapter 14 for information on using different
waveform views.
