the " " position then push the " FUNC. button "
( 3-7, Fig. 1 ) for display show " ".
4)when the resistance value is less than 10 ohm, the
beeper sound will be generated.
5-5 Diode Test
1)Connect BLACK test lead into " COM " terminal.
2)Connect RED test lead into " V " terminal.
3)Select the " Function rotary switch " ( 3-4, Fig. 1 ) to
the " " position then push the " FUNC. button "
( 3-7, Fig. 1 ) for display show " ".
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.

b. When connected as shown in Fig. 3, a reverse check
on the diode is made. If the diode under test is
good, " OL " will be displayed. If the diode under test
is defective, " .000 " or other numbers will be
displayed. Proper diode testing should include both
steps a. and b. above.
