Entry-level cable testers are essentially continuity testers. A continuity tester is an item of electrical test equipment used to determine if an electrical path can be established between two points; [1] that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the apparatus. [1]
In electronics, a continuity test is the checking of an electric circuit to see if current flows (that it is in fact a complete circuit). A continuity test is performed by placing a small voltage (wired in series with an LED or noise-producing component such as a piezoelectric speaker ) across the chosen path.
A survey without touching anything, and looking at the electrical installation or product before starting any electrical testing. A visual inspection seeks to identify damaged insulation, disconnected wires, incorrect installation, and any other visual issues. Dead testing. Continuity test: a test to check the wiring is correct
The addition of a high-speed switching system to a test system's configuration allows for faster, more cost-effective testing of multiple devices, and is designed to reduce both test errors and costs. Designing a test system's switching configuration requires an understanding of the signals to be switched and the tests to be performed, as well ...
A GCM or ground continuity monitor (also called a ground integrity monitor or ground continuity tester) is an electrical safety device that monitors the impedance to ground of a temporary electrical circuit and can provide indication (or protective trip) in the event impedance rises to an unsafe value. A GCM is either an external testing device ...

A multimeter can use many different test probes to connect to the circuit or device under test. Crocodile clips, retractable hook clips, and pointed probes are the three most common types. Tweezer probes are used for closely spaced test points, as for instance surface-mount devices. The connectors are attached to flexible, well insulated leads ...
