Carrying out a continuity test
Note!
With meshed systems, the test sequence must be carried out at each
separation point.
1. Open the separation point
1
, in order to separate the conductor and
earthing system from each other.
2. Using an ohmmeter, check the resistance value between the connec-
tion element
2
and the opened earthing system
3
.
3. If there is no continuity, then troubleshooting must be commenced.

Carrying out an insulation test
When using the Pro+ and Premium isCon conductors, ASE connection
elements can be used to check the cable insulation. This allows the
detection of items passing through the cable or mechanical penetrations,
e.g. by nails or screws.
