Multimeter test leads. 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 ...

The following items are used for basic measurement of voltages, currents, and components in the circuit under test. Voltmeter (Measures voltage) Ohmmeter (Measures resistance) Ammeter, e.g. Galvanometer or Milliammeter (Measures current) Multimeter e.g., VOM (Volt-Ohm-Milliammeter) or DMM (Digital Multimeter) (Measures all of the above)
A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter , and often suffices for checking for the presence of voltage on a conductor.
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.
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]
