HIPOT TESTING
Step #2: Tape the Power Switch “ON”
Step #4: Select the Correct Voltage
Prepare the unit to be tested by taping the power
switch in the “ON” position (Figure 60). This completes
the circuit inside the equipment and helps insure that
your hipot test includes ALL wires inside the product.
Turn the tester on and set the voltage at recommended
test voltage (Figure 62). The “pre” and “post” tests are
usually performed at different voltages as indicated
below.
NOTE: A continuity test across the two input terminals
can be performed to assure the switch is on and there
is a complete circuit. Continuity indicates all wires are
being tested.
Pre-Service Test:
usually 500 volts
Post-Service Test: usually 1000 volts

Step #5: Perform the Test
Step #3: Connect the Tester
Using the other tester probe, touch all exposed metal
including the handle and any exposed fasteners. If the
tester signals a failure, you will not only have to correct
the original problem, you will have to inspect the
internal wiring for cracked or otherwise damaged
insulation (Figure 63). (Use electrical tape to reinsulate
if necessary.)
Follow the instructions that came with your tester.
Proper connection of the tester typically requires both
terminals of the power plug be connected to the tester
(Figure 61).
NOTE: If you detect a failure, it’s a good idea to retest.
The instruments are sensitive and can sometimes be
set off by static electricity.
