This is NOT a typical DC output voltage
waveform. One output SCR is not function-
ing. Note the increased ripple content. One
SCR gate was disconnected to simulate an
open or non-functioning output SCR. Each
vertical division represents 20 volts and
each horizontal division represents 5 mil-
liseconds in time. The machine was loaded
with a resistance grid bank.

NOTE: Scope probes connected at machine
output terminals: (+) probe to electrode, (-)
probe to work.
