Frequently Asked Questions (FAQs)
1. What is a circuit tester used for?
A circuit tester is a device which is plugged into an electrical socket to make sure it is wired properly. A circuit tester has a series of lights that show the state of the wiring in the outlet, so the technician can verify that it has been installed properly.
2. What testers do electricians use?
Multimeters. An essential part of any electrician's equipment, the multimeter is the best tool for quick and easy measurements of basic electrical parameters.
3. What is the difference between a circuit tester and a continuity tester?
Unlike other testers, a continuity tester is always used when a circuit is turned off—or on wiring or devices that are disconnected from the circuit. If you are using a continuity tester on a device attached to circuit wiring, always turn off the power to the circuit or device.
4. What is a circuit continuity tester?
A continuity tester is an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the apparatus.
