5.3 Resistance of earth connection and equipotential
bonding
The resistance measurement is performed in order to ensure that the protective
measures against electric shock through earth connections and bondings are effective.
Two sub-functions are available:
R LOWΩ - Earth bond resistance measurement according to EN 61557-4
(200 mA),
CONTINUITY - Continuous resistance measurement performed with 7 mA.
See chapter 4.1 Function selection for instructions on
key functionality.
