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 testing leads into the input terminals.
3) Connect the testing leads to the circuit under test. If the circuit is
continuous (no more than approximately 50
Ω
), the buzzer sounds.

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 testing leads into the input terminals.
3) Connect the testing leads to the diode and then read the value when it
stabilizes.

<Forward-bias Diode Test>
Connect the black testing lead to the cathode and the red testing 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.
