Insert the shock-proof plug of the portable test sample into the
test socket of the appliance tester.
The insulating resistance is measured between the bridged LN
conductor and the protective conductor (PE).

Insert the shock-proof plug of the portable test sample into the
test socket of the appliance tester.
RInsu-2
: The insulating resistance is measured between the PE
of the test socket and the secondary side.
RInsu-3
: The insulating resistance is measured between the
bridged LN conductor and the secondary side.

Insert the shock-proof plug of the portable test sample into the
test socket of the appliance tester.
The testing voltage is applied to the bridged L and N conductors
and measured to parts without PE connection.

Insert the shock-proof plug of the portable test sample into the
test socket of the appliance tester according to the connection
diagram.
The testing voltage is applied to the bridged LN conductor. The
insulating resistance is measured between LN and the accessible
conductive parts.
