000.0 KΩ 
660KΩ range
0.000 MΩ 
6MΩ range
00.00 MΩ 
66MΩ range
c. Connect test leads across the resistance under measurement.
d. You can get reading from LCD.
NOTE:
When only the figure “OL” is displayed, it indicates overrange situation and the higher range has to
be selected.
F. Continuity Testing
a. Connect the black test lead to the COM jack and the red test lead to the
Ω
jack.
b. Press
to select , enter the continuity test.
c. Connect test leads across two point of the circuit under testing.
d. If continuity exists (i.e., resistance less than about 50
Ω
),built-in buzzer will sound.
e. You can get reading from LCD.
NOTE:
If input open circuit(or the circuit resistance measured is higher than 660Ω,then the figure “OL” will
be display.
G. Diode Testing
a. Connect the black test lead to the COM jack and the red test lead to the jack.
b. Press
to select , enter the diode testing.
c. Connect test leads across to the anode, the black lead to the cathode of the diode under testing.
WARNING!
When testing the circuit continuity, be sure that the power of the circuit has been shut down
and all capacitors have been discharged fully.
