A conductivity check is a simplified resistance measurement. If a connection has a sufficiently low resistance - below a certain value that is set inside the multimeter - then the multimeter will emit a sound. If there is a high resistance between the two points of measurement, the multimeter will do nothing. Some common checks that are done with a conductivity test:

• Check whether a breaker, fuse or switch is working. A fuse should have conductivity if it is still good. If it fails a conductivity test then it needs to be replaced and the reason for its failure investigated.
• To test quickly whether a connection to a busbar or between two wires in a circuit was done properly.
• To test whether a wire or system component is a part of a circuit. Often times wires are not properly identified, but a quick conductivity can often identify where that wire leads and to what it is connected.
