Prokit's Industries 3PK-9912 - Manual (Page 10)

The input voltage should be between 200mV and 10V rms. ac. If the voltage is
more than 10V rms. reading may be out of the accuracy range.

AUDIBLE CONTINUITY AND DIODE TEST
1.
2.
3.
4.
Connect red test lead to “
Ω” jack, black test lead to “COM” jack. The
polarity of red lead connection is positive “+”.
Set range switch to “ / ” position and push the FUNC. button to
select audible continuity or diode test mode.
If audible continuity is selected, connect test leads to two points of circuit
to be tested. If continuity exists, built-in buzzer will sound.
If diode test mode is selected, connect the red and black leads to the
anode and cathode of the diode under test. The forward voltage drop of
this diode in V will be displayed.
