Ω
0.2A: CONTINUITY TEST ON EARTH, PROTECTIVE AND EQUALIZING
POTENTIAL CONDUCTORS (M72, M74, M75)
The measurement is performed with a test current higher than 200 mA (R<5
Ω
) and open
circuit voltage ranging from 4 to 24V DC according to EN 61557-2 and VDE 0413 part 4.
CAUTION
Before performing the continuity test make sure that no voltage is present at the
ends of the conductor under test.

Ω
0.2A test
1.
Turn on the instrument
2.
Press the arrow keys to select
Ω
0.2A
3. Insert the black and green cables in the corresponding input terminals of the instrument
4. If the cable length is not sufficient to perform the test, extend the black one
5. If necessary insert the croco clips on the test probes
6. If the measuring cables being used have not been calibrated, first calibrate them as
described in paragraph 4.8.1
7. Connect the instrument’s terminals to the ends of the conductor on which the continuità test
must be performed (see Fig. 8)
