Note
:
We recommend that crocodile clips are used to attain a good contact with the
conductor under test. Indeed in this test the instrument gives as final result the
maximum measured value of R+ or R- and using test leads instead of crocodile clips
could give you a faulty result due to a faulty contact between the test leads and
conductor under test.
The displayed result can be stored pressing the
SAVE
key
twice
(according to
paragraph 9.1).
