PE conductor resistance (MI 3100 SE only)

In TN system instrument measures the resistance of the protection conductor from the power
transformer to the measurement site.
In TT system the resistance of protection conductor from mains outlet to earth electrode and
back to the power transformer via soil and the transformers earthing system is measured.
See chapter 4.2 Function selection for instructions
on key functionality.
