Continuity Testing (
Ω
) (See fig.2)
The continuity tests are activated when the probes
make contact of less than a few k
Ω
. The test
operates without the need to press the
TEST
button. When the test leads are removed the
reading will hold for a few seconds and then reset.
To recall the last result press the key. This
range is not suitable for diode testing since the
automatic contact detector will not be activated
when connected to a diode.
1.
Set the selector switch to
Ω
.
2.
Connect the test leads.
3.
The test will activate automatically.
4.
After the test probes are disconnected, the
reading will be held for a few seconds.
Zeroing of Test Lead Resistance
The resistance of the test leads can be nulled on the
continuity range (up to 9,99
Ω
). The null information
is retained in non-volatile memory and so will be
remembered when the instrument is switched off.
1.
Select the Continuity range.
2.
Short the test leads across a known good
conductor using prods.
3. When the reading
has stabilised, press
the
TEST
button.
The zero
offset
symbol will
appear.
4. To release the zero
offset press the test
button again.
The continuity range
features a range lock
facility. To
LOCK
the
continuity range press
the key, the
LOCK
symbol will appear. To
scroll through the available ranges press the
key. To de-select the
LOCK
feature hold the
key down.
