Specifications

How is continuity tested?

• Probe Contact: Touch the two probes to two points in the circuit.

• Resistance Detection: The internal circuitry of the tester detects the resistance between these two points.

• Buzzer Feedback: If the resistance is below a preset threshold (usually a few tens of ohms), the buzzer will sound, indicating that the circuit is conductive.
