 In "AC" mode, only can input "AC", if not, will damage the meter.
E. Resistance Measuring
WARNING!
When measuring in-circuit resistance, be sure the circuit under test has all power removed and
that all capacitors have discharged fully.
a. Connect the black test lead to the "COM" jack and the red test lead to the "V/

range ,Press "NEAR" to restore "Auto range"
Manual range: ( Connect the red lead to black leads, will display the
measure range)
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 discharged fully.
a. Connect the black test lead to the "COM" jack and the red test lead to the "V/
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 50Ω), built-in buzzer will
