Circuit Tester

To use a circuit tester, begin by protecting yourself from electrical shocks by using a circuit tester with an insulated grip. Insert the probe into the main holes of the wall outlet, and monitor the voltage. After checking the amount of voltage, gently remove the probes from the power outlet. 

Before testing your circuit, ensure that your circuit tester is insulated. Hold the insulated part to protect yourself from all types of electrical shock. Most circuit testers come with insulated parts, but when checking the circuit, avoid touching the exposed metallic parts of the probe for additional security.

Then insert probes into each main hole of the wall outlet. It is not necessary to put probe into the ground if you have a probe on the outlet. Follow the directions given by the manufacturer when inserting the probes.

Finally, view the voltage indicator on the tester to monitor the amount of voltage coming from the outlet. The amount of voltage varies based on the type of outlet used. Failure to obtain enough voltage is a sign of electrical shorts or leakages. If you cannot obtain the required voltage, check your circuit to ensure the sufficient flow of power. After testing your circuit, remove the probes from the power outlet gently. Do not pull the probes harshly because they can stick in or tear a connector in the outlet.
