Continuity Check; Diode Test - Lutron Electronics DM-9961 Manual

5-5 Continuity Check

1)Connect BLACK test lead into " COM " terminal ( 3-11,
Fig. 1 ).
2)Connect RED test lead into " Ω " terminal ( 3-12, Fig. 1 ).
3)Select the " Function rotary switch " ( 3-8, Fig. 1 ) to
the " " position, push the
" Ohm/Diode/Buzzer Button " ( 3-7, Fig. 1 ) for display
show " ".
4)when the resistance value is less than 20 ohm, the
beeper sound will be generated.

5-6 Diode Test

1)Connect BLACK test lead into " COM " terminal ( 3-11,
Fig. 1 ).
2)Connect RED test lead into " Ω " terminal ( 3-12, Fig. 1 ).
3)Select the " Function rotary switch " ( 3-8, Fig. 1 ) to
" Ohm/Diode/Buzzer Button " ( 3-7, Fig. 1 ) for display

4)a. When connected with polarity as shown in Fig. 2, a
forward current flow is established and the approx.
Diode Forward Voltage (VF) value in volt will
appears on the display reading. If the diode under
test is defective, " .000 " or near " .000 " value
( short circuit ) or " .OL " ( open circuit ) will be
displayed.
