Error Messages
There are additional ERROR messages which may appear on the
display during this operation which were not covered previously:
Test Not Running! Check test cable connection

This message indicates that the test set has sensed that cur-
rent is not flowing properly in the breaker under test and that
there is either an open or short circuit between the TS-31 and
the breaker trip unit.
Function Not Available
Press ENTER to continue
You will get this error message if you enter a choice that is not
available, such as entering “G” in step 6 for ground fault test on
a catalog number that does not have the ground fault function.
Inconclusive Test, check settings

This warning will appear if you attempt to run a short time test
with the instantaneous pickup set equal to or below the short

the test can still be run. However, passing or failing the test
may not be conclusive.
