Circuit Continuity Test - Mastech MS2225A Operation Manual

4.20 Circuit continuity test

Electric shock.
For the circuit continuity test, the circuit power should
be disconnected, and the capacitor in the circuit
should be completely discharged.
1) Insert the black probe into COM jack, and insert the red
probe into INPUT jack.
2) Turn the change-over switch to the
3) Press "FUNC" button to switch to the status of
circuit continuity testing.
4) Connect the probes to both ends of the circuit for
measurement.
5) If the resistance of measured circuit is less than 50Ω,
the buzzer inside the meter will make a sound.
6) Read the resistance value of the circuit from LCD.
Note:
If the probe is open-circuited or the resistance of the
measured circuit is greater than 600Ω, the "0L" will be
displayed.
WARNING
