For using the 3-pole measuring lead observe the following:
If the symbol „
“appears, L
1
is connected to the higher potential. If the display
shows „
“L
2
is connected to the wire with the higher voltage with respect to the
reference point PE wire. Versions CH/GB:
L1, approx. L2.
ATTENTION! When using the 3-pole measuring lead, take care to have the
correct connection of the PE-wire to the mains, or else the specified
assignments are invalid! It must not be assumed that there is no risk in
touching the other wires. In position L-N no assignment is possible. In
combination with the display of the insulation resistance R
ISO
this signal
indicates the rigidly assigned L wire!
