10.2.5 RISO – L-N
This measurement is used to test the insula-
tion of, for example, extension cords and
multiple outlets (via optional adapters) with-
out circuitry (e.g. glow lamps).
Test voltage is applied between L and N to
this end, and insulation resistance is mea-
sured.

Insert the test object’s mains plug into
the test socket.
➭
Connect the probe to the red probe
socket.
Procedure
