Now it’s time to insert the red lead into the vertical slot of the wall outlet, make sure to insert it into the slot located on the right.
Once this is set, you are ready to begin testing. Each multimeter is different which means yours may read 0.0 VAC, VAC, or only 0.0. So make sure the digital multimeter is in this setting. As mentioned above, you will be using the “VAC” or volts option on the multimeter. Note – The red lead may have a red ring around the connector and the black lead may have a black ring. Next, you will need to connect the black lead, this is done by connecting it to the “com” label. Finally, examine the readout on your meter, this should show your household voltage.Ĭlick here to order the Owon B35 Explain the logic behind Testing an Electrical Outlet Using a Digital Multimeter: The first step when testing an electrical outlet is to locate the multimeter’s connector labeled “volts” and insert the red lead into it. Then, carefully insert the black probe into the left slot of the outlet.Ħ.
Next, insert the red probe into the right slot of the outlet.ĥ. After that, connect the probes to the proper inputs: COM for the black lead and Volts for the red lead.Ĥ. Note: the maximum voltage for each set, household current is approximately 120 volts, set the dial accordingly.ģ. (Need a new one? Check out our multimeter page.)Ģ.

Here’s how to check your electrical outlet using a digital multimeter: If you want to know more about AC and DC power, this article is a must-read, The War of the Currents: AC vs. Testing an electrical outlet using a digital multimeter in your home, you will need to use the VAC reading available on the device because you are looking for a measurement of Alternating Current Voltage. A digital multimeter gives automatic, quick readings that display VAC (volts alternating currents), VDC (volts direct current), and ohms. These diagnostic steps are used to help locate electrical problems in a number of different sources.
