Continuity Measurement
• Turn the rotary range switch to the
range.
• Insert red test lead to the red "+" input jack
and the black lead to the black "COM" input
jack.
• Bring the test probe tips into contact with the
sample under test.
• If the resistance is less than 40Ω, the beeper
emits a continuous sound.
WARNING: Immediately unclamp the
meter from the conductor under test if
overload "
WARNING: When testing continuity,
make sure that there is no power in
the tested sample or circuit (dead cir-
cuit). This may be checked by using
the voltage functions.
