Continuity Testing
a. Connect the black test lead to the “COM” jack and the red test lead to the “V/
Ω
” jack.
b.to select , enter the continuity test, Connect test leads across two point of the circuit under testing.
c. If continuity exists (i.e., resistance less than about 50 Ω ), built-in buzzer will sound.
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
anode “+” )
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.
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”
