2)
Conduct a simulated PASSING test by setting all three switches of the HTT-
1S to the PASS (green) setting and initiating a ground bond test by starting your
ground bond tester.
a)
Your ground bond tester should indicate ‘PASS’.
3)
Conduct a simulated GROUND OPEN test by setting the GROUND switch on
the HTT-1S to ‘FAIL’. (All other switches on the HTT-1S should be set to
‘PASS’.) Begin testing by starting your ground bond tester.
a)
Your ground bond tester should indicate ‘FAIL’, stop testing, and sound a
buzzer or otherwise warn the operator of a problem.
Unanticipated Results
The HTT-1S test may cause your tester to give results not consistent with those
anticipated by the switch setting of the HTT-1S. Until the problem is resolved,
your tester should be removed from service.
If there is an unexpected leakage or ground result, first check the hipot or ground
bond trip limit settings are correct.
If it is not detecting hipot failures, make sure testing voltage is above 750Vac.
If there is a question regarding the proper operation of the HTT-1S,
troubleshooting information in Section 4 can be used to verify proper operation of
the HTT-1S.
