output current is limited to 7.5 mA. When such a trip-out
occurs, before approaching the equipment, apply the
grounding stick to the high voltage terminal to discharge the
test setup as all stored energy may not be dissipated by such a
failure.
NORMAL SHUTDOWN PROCEDURE
When the test has been completed, follow this shutdown
procedure:
1.
Set the voltage control to zero.
2.
Open the AC "ON" switch or the OUTPUT "ON" switch
or both.
3.
When the voltmeter indicates that voltage has decreased to
a value of less than half the voltage used during the test,
use an insulated grounding stick to apply a direct short
circuit to all ungrounded terminals of the apparatus being
tested.
4.
Disconnect cables in the following sequence; first, the
input cable; second, the output cable (including the guard
if in use), finally, the ground cable.
5.
Apply ground bonds to the equipment that has been
disconnected.
INTERRUPTING A TEST
At any time, the AC "ON" or HV "ON" switches can be
opened manually to interrupt a test, provided that the
grounding stick is applied afterward to discharge any stored
energy as described in the normal shutdown procedure.
For any circumstances requiring that a test be stopped
immediately, the procedure is to apply the grounding stick
directly to the high-voltage terminal. This action will remove
