G. Diode Testing
a. Connect the black test lead to the “COM” jack and the red test lead to
the “V/
Ω
” jack (the red lead being the anode “+” )
b. to select , enter the diode testing.
c. To test forward bias, connect red test lead across to the anode and the
black lead to the cathode of the diode under testing.
d. To test reverse bias, connect test red lead across to the cathode, the black lead to the anode of the
diode under testing.
e .Tested diode forward voltage should read between 0.5 and 0.8 volts. Reverse bias should bead “OL”
for infinite reading.
H. Capacitance Measuring
a. Connect the black test lead to the “COM” jack and the red test lead to the “V/
Ω”
jack.
b. Select “ ” to enter the capacitance measurement.
c. The tester default auto range status; choose manual range by pressing upward and downward key;
Auto range by press the key “Auto Range”
Manual range: 0.000nF

6.600nF range
00.00nF

66.00nF range
000.0nF

660.0nF range
0.000uF

6.600μF range
WARNING!
When measuring in-circuit diodes, be sure the circuit under test has all power removed and that all
capacitors have discharged fully.
WARNING!
To avoid electric shock, be sure the capacitors have been discharged fully before measuring the
capacitance of a capacitor.
