Measurement where connection is not at a
Power Socket
1. Select Loop L-PE 0.1Ω or L-PE xtra as
appropriate.
2. Firmly connect the red lead to phase and
the green lead to earth. Connection to
neutral with the black lead is only required
for the Loop L-PE xtra range.
3. Supply voltage is displayed.
4. Press the TEST key. Test progress is
displayed.
5. Measured loop value is displayed.
If desired the test can be repeated by pressing TEST
again.
After a Loop L-PE xtra 0,01Ω test, the additional
parameters above may be stepped through by
repeatedly pressing the enter key.
The results of the L-PE xtra test will be shown in the
following order:

To access the individual Live, Earth and Neutral
resistances 1, 2 and N for the circuit press the enter and
the backlight keys together, (a long beep will sound).
The results can be stepped through using the enter key.
Press the enter and backlight key together again to
return operation to the previous mode.
