4.17 TESTING CONTINUITY
WARNING
Beware of Electrocution.
Make sure that the power of the circuit has been turned off
and the capacitors have been fully discharged before testing
the continuity of a circuit.
4.17.1 Plug the black test lead into the
COM
jack and the red test
lead into the
INPUT
jack.
4.17.2 Set the rotary selector to the range position.
4.17.3 Press the "
SEL
" button to switch to
continuity test.
4.17.4 Connect the test leads to the two ends of the circuit for
measurement.
4.17.5 If the resistance of the circuit being tested is less than 40
Ω
,
the built-in buzzer will maybe sound.
4.17.6 Take the reading on the LCD.
NOTE:
If the test leads are open or the resistance of the circuit is over
400
Ω
, “OL” will appear on the LCD.

4.18 MEASURING CAPACITANCE
WARNING
Beware of Electrocution.
To avoid electric shock, make sure that the capacitors have
been fully discharged before measuring the capacitance of a
capacitor.
4.18.1 Plug the black test lead into the
COM
jack and the red test
