TYPICAL OUTPUT VOLTAGE WAVEFORM – MACHINE LOADED
TROUBLESHOOTING & REPAIR
20 volts
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 5 milliseconds in
time. The machine was loaded with
a resistance grid bank. The CV-400
meters read 400 amps at 36 VDC.
Note: Scope probes connected at
machine output terminals: (+) probe
to positive terminal, (-) probe to neg-
ative terminal.
