Touch the test probe tips to the circuit or wire you wish to
check,
If the resistance is less than approximately 35
, the audible
signal will sound. If the circuit is open, the display will indicate
“
OL
”,
Having done the measurement disconnect the test leads from
the meter.
5.8 Diode Measurements
ATTENTION!
Measurements must not be realised in live circuits. Capaci-
tors must be discharged.
In order to realise diode test it is necessary to realise the follow-
ing actions:
Set the function switch to the green
Ω
CAP
position,
Insert the black test lead banana plug into the negative
COM
jack and the red test lead banana plug into the positive
jack,
Press the
MODE
button to indicate
and
V
on the display,
Touch the test probes to the diode under test. Forward voltage
will typically indicate 0.400 to 0.700V. Reverse voltage will in-
dicate “
OL
”. Shorted devices will indicate near 0V and an open
device will indicate “
OL
” in both polarities,
Having done the measurement disconnect the test leads from
the meter.
