GETTING STARTED

6. Only connect the test leads to the HIGH
VOLTAGE terminals before the start of a test.
Keep the test leads disconnected at all other
times.
7. Always press the STOP button when pausing
testing.
8. Do not leave the hipot tester unattended.
Always turn the power off when leaving the
testing area.
9. When remotely controlling the hipot tester,
ensure adequate safety measures are in place to
prevent:
 Inadvertent output of the test voltage.
 Accidental contact with the instrument during
testing. Ensure that the instrument and DUT are
fully isolated when the instrument is remotely
controlled.
10. Ensure an adequate discharge time for the
DUT.
When DCW or IR tests are performed, the DUT,
test leads and probes become highly charged.
The GPT-9500 has discharge circuitry to
discharge the DUT after each test. The time
required for a DUT to discharge depends on the
DUT and test voltage.
Never disconnect the hipot tester before a
discharge is completed.
