F. Continuity Testing
(see figure 7)
Warning
To avoid possible damage to the Meter and to the
device under test, disconnect circuit power and
discharge all high-voltage capacitors before testing
diodes and continuity.
To test for continuity, connect the Meter as below:
Insert the red test lead into the
terminal and the
black test lead into the
COM
terminal.
Set the rotary switch to .
Connect the test leads across with the object being
measured.

Open-circuit voltage is approx. 3V.
When continuity testing has been completed,
disconnect the connection between the testing leads
and the circuit under test.

The buzzer does not sound when the resistance
value is >100 . The circuit is disconnected.
The buzzer sounds continuously when the resistance
value is 10 . The circuit is in good condition.
The buzzer may or may not sound when the
resistance value is between 10
~100 .

To avoid harm to yourselves, never attempt to input
an effective voltage over 60V in DC or 30V in AC.
