How to Use a Circuit Tester


If you are working on the construction site of a new building or just remodeling your current house, you will want to use a circuit tester. A circuit tester will check the outlets in the building to see if they are receiving any sort of electrical flow. This is good knowledge to have because you will want to make sure all the outlets are working properly before you send the electricians home.

  • Keep hold of the insulated portion of the circuit tester. This is to protect you from any sort of electronic shock. The majority of the circuit tester is insulated, but do not touch the exposed metal of the probes while checking the circuit.

  • Insert one probe into each of the main holes of the wall outlet. You do not need to put any into the ground hole (if you have one on the outlet).

  • View the display to see what the voltage is. The amount of voltage can vary depending on the kind of outlet and what it is used for. This may point out any electrical short or leak if you are not obtaining enough voltage in the given outlet.

  • Remove the probes from the power outlet gently. If you pull too hard, they may become stuck and tear a connector inside of the outlet.
