4.3.5 Continuity Check ( )
CAUTION
To avoid damage to instrument
Turn off the power to the circuit under test before starting measurement in order to prevent any
excessive voltage from being applied to the instrument.
1) Turn the function switch to the “ ” position.
2) Plug the test leads into the input terminals.
3) Connect the test leads to the circuit under test. If the circuit is continuous
(no more than approximately 50
Ω
), the buzzer sounds. Test leads

4.3.6 Diode Test ( )
CAUTION
To avoid damage to instrument
Turn off the power to the circuit under test before starting measurement in order to prevent any
excessive voltage from being applied to the instrument.
1) Turn the function switch to the “
•
” position.
Press the SELECT key to select Diode test.
(The display shows the
symbol.)
2) Plug the test leads into the input terminals.
3) Connect the test leads to the diode and then read the value when it
stabilizes.
Test leads
Red Black
<Forward-bias Diode Test>
Connect the black test lead to the cathode and the red test lead to the anode.
Silicon diodes should give a reading of approximately 0.5V and light-emitting diodes a reading
between approximately 1.5V and 2.0V.
