After the test simulation has been cancelled (letting go of the test button), the
test is concluded and the equipment goes back to normal operation.
Faulty equipment jeopardises system safety.
■
■
If the conductivity electrode does not behave as described above, it may be faulty.
■
■
Perform failure analysis.
