Turn the dial of your multimeter and set it to120 volts. Insert the metal tip of the red probe into any of the slanted 120-volt slots, and slip the metal tip of the black probe into the middle (ground) slot. Your multimeter should read approximately 120 volts AC. If it does not, then that circuit is defective.
