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.Click to see full answer. Similarly, you may ask, what is the purpose of continuity testing?A continuity test is an important test in determining the damaged components or broken conductors in a circuit. It can also help in determining if the soldering is good, if the resistance is too high for flow of current or if the electrical wire is broken between two points.Also Know, what is the difference between a circuit tester and a continuity tester? A continuity tester is a device that is powered by batteries and has a probe at one end and a cord with either an alligator clip or another probe at the other end. 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. Also Know, how do you use a continuity tester? To use a continuity tester, unplug the appliance and disassemble it to get at the component you want to test. Fasten the clip of the tester to one wire or connection of the component, and touch the probe to the other wire or connection.What does a reading of 0 ohms mean?Resistance is measured in ohms with no current flowing through the circuit. It indicates zero ohms when there is no resistance between the test points. This shows continuity of current flow in a closed circuit. It indicates infinity when there are no connections in the circuit that is as in an open circuit.
