Features:
Equipped with a buzzer that emits a 100-decibel sound, this continuity tester delivers a clear audio signal, while the integrated indicator light ensures visual confirmation during testing.
1. Easy to operate: Insert the tester, touch both ends of the wire under test—if both sound and light alarm are triggered, the connection is conductive; if not, there is no continuity.
2. Powered by a built-in 9V battery, which is easily replaceable via the detachable cover. The device consumes no power when not measuring, as the circuit remains open without connection at the red and black ends.
3. Designed to run at approximately 20mA loop current when measuring. Not recommended for testing microelectronic components or delicate .
