If it has many ranges, set the dial to the minimum range. Set the dial of the multimeter to resistance mode Ω.
First de-energize the circuit, if it has any power source.Steps for continuity test using an ohmmeter Related Post: How to Test a Relay & Relay Coils by Multimer?Īn Ohmmeter can also be used to determine the circuit whether it is a closed or open circuit, which is the main purpose of a continuity test.The result is always the same except some cases like diodes which allow the flow in only one direction. The continuity in non-directional, it does not matter which probe should be connected to which side. If the meter does not beep & show 1 or OL, it means the path is broken (open) or the component does not allow the flow of current.If the meter shows 0 and beeps, it means the path is complete (close) or the component allows the flow of current.Now connect the probes to both ends of the component or wire that you want to test.If the meter beeps or gives reading 0 that means the meter works fine. Insert the red probe into the V, Ω port.Insert the black probe into the COM port.Set the dial of the multimeter in continuity mode (continuity mode is shown by the symbol of sound).De-energize the circuit, if it has any power input.
These circuits can be distinguished using the continuity test. Usually, there is a buzzer or led in series (inside continuity meter) to identify if the current flows through it or not.Ī close-circuit provides a closed path for the current flow & an open circuit does not allow the current flow. The current flow between these two points determines if it’s an open or closed circuit. In a continuity test, a small voltage is applied to the two points of the circuit that need to be checked. Continuity Test For Fuse, Switch, Cables Etc.Ĭontinuity Test is the testing of an electrical circuit to determine if the current can pass through it (known as close or complete circuit).
