How do I use my digital Multimeter to measure the voltage in my wall outlet at home?
A. If you have an auto ranging meter set the function dial to VAC. Insert the red test lead into the red jack labeled with a “V” and insert the black Test lead into the black colored jack label “COM”. Insert the black test probe tip into the neutral side of the circuit. Touch the red test probe Tip to the “hot” side of the circuit and take the reading on the display. If the reading is Proceeded by a (-) negative sign switch the leads in the wall outlet to obtain a positive reading. If your Multimeter is manually ranging, set the function switch to the highest VAC range position. Insert the red and black leads into the positive Negative sides of the outlet as described above. Read the voltage on the display. Use the function dial switch to successively lower the VAC position to obtain a higher resolution reading.
