5)a. When connected with polarity as shown in Fig. 2, a
forward current flow is established and the approx.
Diode Forward Voltage (VF) values in volt will display
on the display reading. If the diode under test is
defective, ".000" or near ".000" value (short circuit) or
" 1 " (open circuit) will be displayed.
Fig. 2
b. When connected as shown in Fig. 3, a reverse check on
the diode is made. If the diode under test is good,
" 1 " 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.
