- Plug the two tester leads into the multimeter.
- Insert the two test leads (one each) into the two "hot" slots of the outlet.
Hereof, how do you test a 240 volt with a multimeter?
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.
Also Know, what does a 220 volt plug look like?
The Difference Between a 110 and a 220 Outlet Virtually all 110 volt outlets look the same. The 220 outlet is larger, and it's usually round and black or dark brown, not white. It can have three slots or four. Four-slot outlets have a ground wire.
You can use either a current tester or a voltage meter to determine if an electrical cable is hot. Keep in mind that it is possible for more than one wire to be live. Touch the tip of the meter or tester to the screw where the wires are attached. Go slowly and keep your eyes and ears open.
