During the measurement, the entire length of the wire is to be moved in sections. If a
change in resistance is noted while part of the wire is being moved, the fault must be
found with a detailed troubleshooting procedure. Defective cables must not be
repaired. They must be replaced in all cases.
The resistance of the PE connection must be checked by a measurement according to
fig. 1.
