13. If the instrument detects an
extremely high earth
resistance, so that it deems
the earth conductor or the
earthing absent, it does not
perform the test and displays
the message reported here
to the side. Check the
efficiency of the protective
conductor and the earthing

14. If the instrument detects that, in
case the test should be
performed, a contact voltage
higher than the set limit would
build up in the system being
tested, it does not perform the
test and displays the message
reported here to the side.
