A continuity test is used to verify the integrity of connections by making a high
resolution resistance measurement. This is especially important for checking
Protective Earth connections.

Note
In countries where electrical circuits are laid out in a ring, it is
recommended that you make an end-to-end check of the ring at the

position.
2. Use the L and PE (red and green) terminals for this test.
3. Before making a continuity test, use the Zero adapter to zero the test

leads. Press and hold until the ZERO annunciator appears. The
tester measures probe resistance, stores the reading in memory, and
subtracts it from readings. The resistance value is saved even when power
is turned off so you don’t need to repeat the operation every time you use
the instrument.
