b. to select , enter the diode testing.
c. Connect test red lead across to the anode, the black lead to the cathode of the diode under testing.
d. Connect test red lead across to the cathode, the black lead to the anode of the diode under testing.
e .Tested diode, forward voltage low 30mv,there is sound indication ,then can finish the testing quickly
without view the screen.
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, enter the capacitance measurement.
c. The tester default auto range status, and manual range by press upward and downward key, Auto rang
by press the key “NEAR”
Manual range: 0.000nF 6.600nF range
00.00nF 66.00nF range
000.0nF 660.0nF range
0.000uF 6.600µF range
00.00uF 66.00µF range
000.0uF 660.0µF range
0.000mF 6.600mF range
00.00mF 66.00mF range
d. Before connect test leads across two sides of the capacitor under measurement, be sure that the
capacitor has been discharged fully.
Note:
WARNING!
To avoid electric shock, be sure the capacitors have been discharged fully before measuring the
capacitance of a capacitor.
