Initial Checkout Procedure
The following procedure will verify that the
Tester is working correctly. We recommend that
this procedure be conducted periodically to
ensure proper operation of the Tester.
The following items are needed to conduct this
procedure:
A three inch piece of 18 AWG insulated
hookup wire with each end stripped back
½".
A test lead with a banana plug on one end.
The other end will be clipped to the
alligator clip end of the black test lead
supplied with the HT-2800.
CAUTION
High voltage (up to 2800 Volts
DC) generated by the HT-2800 is
exposed during this test. A risk
of shock exists. Exercise care
when using the HT-2800.

LED may also
light.
Note: The following procedure
tests the "Hipot Breakdown"
circuit of the HT-2800 and involves
high voltage. The only exposed
parts during this test are at ground
potential. However, the voltage
inside the High Voltage Device
socket may be as much as 2800
volts. Proceed with caution.
22.
Make sure the Test Return Lead is still
plugged into the
RETURN
jack on the
front panel.
23.
Make sure the
Ground Check
switch on
the rear panel is Off.
