Protective earth conductor resistance measurements of test objects with fixed connections
Where possible for appliances with fixed connections, supply them with power in the test object’s
current circuit.
Set the automatic test sequence „Fixed connection (protection class I)“ via the
Test-Master app
. Sample
the housing parts with the test probe.
Select „Fixed connection“ under RPE measurement for individual measurements on the appliance.
If this is the case, the PE is measured via the test device mains connection, the installation in the system
and the test object mains connection.
That is why the limit value is higher than for direct measurement.
9.4
Protective earth conductor resistance measurement of extension cables
In extension cables and power strips, the presence of the PE conductor must be proven at every shock-
proof socket.
Set the automatic test sequence „Extension (protection class I)“ in the
Test-Master app
. Sample all PE
conductor contacts.
For individual measurements on the appliance, select „Plug“ under RPE measurement and contact the
PE conductor with adapter [A1] or [A2] (TG Basic 2).
Use the included test cable for measurement with the TG basic 2+.
