This is the typical DC open circuit
voltage waveform generated from a
properly operating machine. Note
that each vertical division represents
20 volts and that each horizontal divi-
sion represents 2 milliseconds in
time.
Note: Scope probes connected at
machine output terminals: (+) probe
to positive terminal, (-) probe to nega-
tive high inductance terminal.
