Continuity Measurements
WARNING: Please remove power to the circuit under test and discharge all capacitors
before taking resistance or continuity measurements. The meter will display OL if the circuit
under test is an open circuit or if the measurement exceeds the maximum range of the meter.
Do not input a voltage >30V AC or DC.
1.
Turn the function switch to the Continuity
position.
2.
Use the M (mode) button to select the continuity display
icon.
3.
Insert the black test lead banana plug into the negative (COM) jack. Insert the red test
lead banana plug into the red (Ω) jack. See Fig. 5.
4.
Touch the test probe tips across the circuit or wire.
5.
If the resistance is < 10Ω, the meter will beep. If the resistance is > 70Ω, the meter will
not beep. If the resistance is between 10 and 70Ω, the meter will stop beeping at an
unspecified point.
