• Capture and trigger on falling edge of the DC Link current waveform at
ACB test point “Idc1”.
• Label the waveforms as “Vuv”, “Vuvs” and “Idc1”.
• Save the worksheet as “Drift @ 15 Degree Lead Angle”, for example.

While performing a live synchronous transfer:
• Capture motor voltage at ACB test point “Vuv” & bypass voltage at ACB
test point “Vuvs”.
• Capture and trigger on falling edge of the DC Link current waveform at
ACB test point “Idc1”.
• Label the waveforms as “Vuv”, “Vuvs” and “Idc1”.
• Save the worksheet as “Synch on Motor 01”, for example.
