c. Connect the test leads to the device being measured.
d. Once connected the resistance will be displayed on screen.
NOTE:
When only the figure "OL" is displayed, it indicates over range situation and the higher range has to be
selected.
F. Continuity Testing
WARNING!
When testing the circuit continuity, be sure that the power of the circuit has been shut down and all
capacitors have been fully discharged.
a. Connect the black test lead to the "COM" jack and the red test lead to the "V/
b. Press to select
c. Connect test leads across two point of the circuit being tested.
d. If continuity exists (i.e., resistance less than about 50Ω), the
built-in buzzer will generate an audible tone.
e. You can also get reading from the LCD indicating continuity.
G. Diode Testing
a. Connect the black test lead to the "COM" jack and the red test lead to the "V/
b. Press to select
c. Connect test red lead to the anode of the diode under test.
d. Connect the black lead to the cathode of the diode under test.
E .If the tested Diode has forward voltage of 3V or more, an audible tone will sound, indicating proper
diode operation.
F.The capacitance of a capacitor should be tested separately.
