How to use a multimeter to check a wire for continuity

Home > Search > How-to

A wire is working properly when it has continuity. A multimeter can be used to test a wire for continuity.

  1. Turn on your multimeter. The multimeter should read 1.
  2. Set your multimeter to the test continuity setting.

  1. Place both ends of the multimeter leads on each end of the wire.
    • If the multimeter changes from 1 to 0, the wire has continuity.
    • If the multimeter does not change from 1 to 0, the wire does not have continuity.
