5.2 Insulation resistance
The insulation resistance measurement is performed in order to ensure safety against electric
shock through insulation. Typical applications are:
 insulation resistance between conductors of installation,
 insulation resistance of non-conductive rooms (walls and floors),
 insulation resistance of ground cables and
 resistance of semi-conductive (antistatic) floors.
See chapter 4.2 Function selection for instructions on
key functionality.
