Figure 213 - Sample Waveforms
Sample Waveforms captured on ACB test points showing incoming line voltage
phasing [Ch1: V2uv (red), Ch2: V2vw (yellow), Ch3: V2wu (blue)]
Sample waveforms captured on ACB test points showing
20 deg Phase Shift between Master and two Slave Bridges
[Ch1-Master: V2uv (red), Ch2-Slave 1: V3uv (yellow), Ch3-Slave 2: V4uv (blue)]
TIP Use the same settings on the oscilloscope when capturing waveforms for the
two Slave bridges. If you are using a 2-channel oscilloscope, then first capture
two waveforms and move them onto a wavestar worksheet and after that
capture the remaining waveforms and move them onto the same wavestar
worksheet.
