Continuity Measurement
Test continuity between two
points of a circuit.
WARNING! To prevent electric shock, turn
off all power and fully discharge capacitors
on the circuit under test before measuring.
1.
Plug black test lead into COM Jack.
Plug red test lead into Input Jack.
2.
Turn the Rotary Switch
to the
position.
3.
Press FUNC until
Diode Measurement
Test voltage drop in diodes.

is displayed.
For technical questions, please call 1-888-866-5797.
4.
Connect the test leads across
the circuit to be measured.
5.
Read measured resistance on the
Display. If the measured resistance
is less than 50Ω, Meter will beep.
6.
When testing is complete, turn
Rotary Switch to OFF, remove
Test Leads and store with Meter.
Note: If Test Leads are open or
the resistance of the circuit is out
of range, OL is displayed.
4.
Connect red probe to diode's anode
and black probe to its cathode.
5.
Read measured forward-biased
voltage drop on the Display.
Note: If the test leads are reversed
or open, OL is displayed.
6.
When testing is complete, turn
Rotary Switch to OFF, remove
Test Leads and store with Meter.
