5.3 Single test
Test steps can be called up in the form of single tests and repeated as often as required. For example, if a limit
value is not complied with during a classified test sequence, the test step concerned can be examined in more
detail using a single test.
During the PE conductor test, the low-resistance continuity of the PE conductor
is tested with a high current (>2 A). This produces heat energy.
If the PE conductor test is repeated very often and without breaks during manual
testing or single tests, the test system will prevent overheating by aborting the
test. A message will appear:
After the test is terminated, testing the PE conductor is permitted again within a
few seconds.
