4.
With voltage control set for 15 kV output, set stabilizer to
"IN". Voltage should drop to about 13.5 kV.
5.
Follow the shutdown procedure given in Section 8.
6.
Connect the high voltage output to ground.
7.
Set the voltmeter range to 7.5 kV and the megohmmeter
range to X1, stabilizer "OUT".
8.
Operate the set and very carefully turn up the voltage
control.
Note that the megohmmeter moves to full deflection.
9.
After reaching full scale on the X1 megohm range,
advance the voltage control to 25: either or both circuit
breakers must trip in 20 seconds or less with a supply
voltage of 117 volts or more. If the supply voltage is
between 105 and 117 the time for tripping may be as long
as 40 seconds.
