Sequence – DUT Connected to Test Socket
Ð Select the test: R PE softkey.
Ð Connect the DUT to the test socket.
Ð
Select measuring range, protective conductor test current, frequency
and measurement duration.
Ð Select test socket or extension cable* as the type of connection
via measurement type.
Ð Start the test: Press the ONSTART key.
Ð After each reconnection to the mains, and as soon as the first
test is started, a mains connection test is executed (see
section 4.1.1).
Ð Contact one of the conductive parts of the housing which is
connected to the protective conductor with the probe.
During measurement, the connector cable must only be moved to
the extent it is accessible during repair, modification or testing.
If a change in resistance occurs during the manual test step of the
continuity test, it must be assumed that the protective conductor
is damaged, or that one of the connector contacts is no longer in
flawless condition.
Ð Measured values are displayed.
Ð End the test: Press the ONSTART key.
Ð Read the measured value and compare it with the table of
allowable limit values.
* Special Case, Connection of Extension Cables
The extension cable plug is inserted into the test socket, and the
probe is connected to the protective conductor contact in the
coupling socket.
