Hipot Breakdown Performance Test
Note: The following procedure tests the "Hipot Breakdown" circuit of the HT-S unit 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 2000 volts AC or 2800 volts DC or up to 3000 Volts
AC and 4200 Volts DC for HT-4200S. Proceed with caution.
1.
Disconnect all leads of the HT-S front panel.
2.
Turn the
Ground Check
switch on the rear panel to the Off position.
3.
Plug the supplied 18 AWG GL Test Lead (Alligator
Clip/Banana Plug ends, black) into the
RETURN
receptacle on the front panel, then connect a bent
paper clip (not provided) to the green alligator clip
on the end of the test lead.
4.
Push the red
RESET
button, then the yellow
TEST
button. After the
Full Voltage
LED lights, and
before the
Hipot Pass
LED has lit, insert the end of
the paper clip into one of the vertical parallel slots
in the High Voltage Device receptacle on the front
panel. Keep fingers away from the alligator clip
and the bare wire.
5. The test should immediately terminate with a buzzer. The
Ground OK
,
Ground Open
,
Full
Voltage
,
Hipot Fail
and red
RESET
LED’s should be lit.
Note: Depending on how the connection between the High Voltage Test Receptacle and the
hookup wire is made, the
Excess Leakage
LED may light, and in some instances, the
Ground
OK
LED may extinguish.
Passage of these tests indicates that the HT-S tester is functioning properly and that it is safe to
use. If the results of the performance test are not in accordance with the above, service is required.
Remove the HT-S tester from service and contact Compliance West USA, Inc. for servicing information.
