4.10 Diode Test
4.10.1 Plug the black probe into the
COM
jack and the
red probe into the jack.
4.10.2 Set the range selector to the range position.
4.10.3 Press the "
FUNC
" key to switch to the test
mode.
4.10.4 Connect the red probe to the anode and the black
probe to the cathode of the diode for testing.
4.10.5 Take a reading in the main display area of the LCD.
1) The meter indicates the approximate forward voltage
drop of the diode.
2) If the test probes are reversed or open, the LCD will
display ‘0L’.
Note:
WARNING
There is the risk of electric shock.
When measuring the continuity of a circuit,
make sure the power is disconnected and the
capacitor on the circuit is fully discharged.
4.11 Circuit Continuity Test
4.11.1 Plug the black probe into the
COM
jack and the
red probe into the
Ω
jack.
4.11.2 Set the range selector to the range position.
4.11.3 Press the “
FUNC
” key to switch to the circuit
continuity test mode.
4.11.4 Connect the test probes to the circuit for
measurement.
4.11.5 If the resistance of the circuit under test is less
than 70
Ω
, the buzzer in the meter will beep.
4.11.6 Read the resistance of the circuit in the main
display area of the LCD.
Note:
If the test probes are open or the resistance of the circuit
under test is over 200
Ω
, “0L” will be displayed on the LCD.
4.12 Resistance Measurement
WARNING
There is the risk of electric shock.
When measuring the impedance of a circuit,
make sure the power is disconnected and the
capacitor on the circuit is fully discharged.
4.12.1
Plug
the
black
probe
into
the
COM
jack
and
the
red probe
into
the
Ω
jack.
4.12.2
Set
the
range
selector
to
the
Ω
range
position.
4.12.3
Press
the
RANGE
”
key
to
select
auto/manual
range.
4.12.4
Connect
the
test
probes
to
the
resistor
or
circuit
under test
for
measurement.
4.12.5Take a reading in the main display area of the LCD.
“
Note:
1) In the manual range mode, if the LCD displays ‘O L’
only, it means the measurement has exceeded the
range and a higher range should be selected.
2) In case of open input, the LCD will display the ‘0L’
over-range mode.
3) If the resistance to be measured is higher than 1M
,
the meter may take a few seconds to get a steady
reading. This is normal for high resistance reading.
