Continuity Testers

A Continuity Tester is a type of electrical testing equipment. Continuity testers are used to test for an electrical path between two given points. If an electrical current is found, the circuit that is being tested on can be safely de-energised before being connected to any other equipment.


A Continuity Tester can sometimes be referred to as an "Electrical Tester", "Voltage Continuity Tester" or a "Circuit Tester".


How do Continuity Testers work?


The test equipment holds an electrical current indicator, which sits between the two test leads and probes. Whilst performing a test, if a circuit is established and a current or voltage is found then the indicator will be activated. This indicator may be in the form a light or buzzer, alternatively there are audible Continuity Checkers that will omit a beeping noise if power or a current is found during.


What are Continuity Testers for?


A Continuity checker is used to perform a continuity test on apparatus, to determine if a connection has been made correctly or if one is apparent between two points. This tester also helps with the indication and detection of two points that are connected, that possibly shouldn't be.
