50 volts | 2 ms |
This is the typical AC output voltage waveform generated from a properly operating machine. Note that each vertical division represents 50 volts and that each horizontal division rep- resents 2 milliseconds in time.
Note: Scope probes connected at
machine output terminals: (+) probe to electrode terminal,
