0 volts

20 volts

5 ms

MACHINE LOADED TO 125 AMPS AT 23 VAC

This is the typical AC output voltage generated from a properly operating machine. Note that each vertical division represents 20 volts and that each horizontal division represents 5 milliseconds in time. The machine was loaded with a resistance grid bank.

Note: Scope probes connected at machine output terminals.
