How to test power outlet with multimeter

Professional supervision advised. Warning: If unfamiliar with electrical safety proced. Also shows potential of outlet and meter se. Free by coupon or very low cost by wallet!


The course was put together with the amateur in mind so it is pretty easy to follow yet powerful and effective.

The black lead will be inserted into the left vertical slot of the wall outlet.

Now it will be time to check to see what reading you are receiving.

This all depends on the power levels the utility companies are supplying. Ever wonder if power is actually reaching an outlet ? Properly use your multimeter also can tell you whether the white and black wires are reverse whether the receptacle is properly grounde and which cable entering the box feeds power to the outlet. If voltage in the circuit is unknown, set the range to the highest voltage setting and set the dial on áš˝. Note: Most multimeters power up in Autorange mode. Prior to performing any electrical work, four methods can help you figure out if that outlet or light box has power running toward or through it. Just remember these outlets should be on while checking so use caution.

Most homes built in the past several decades have fully grounded electrical outlets , recognizable by the third U-shaped receptacle between and below the hot and neutral receptacles. Always test your test equipment for proper operation before use. Working with live electrical current can be very hazardous.


Testing voltage output requires working with electrical current. Do not attempt this measurement without the proper . Now that you know it works, turn your switch on, use the probe to check for power at it, then go . Before you plug the rack into the ac power source, complete the following checks on the ac power . A multimeter is an instrument used to check for AC or DC voltages, resistance and continuity of electrical components, and small amounts of current in circuits. Double check that the test leads are plugged into the common and voltage sockets of the DMM (see photo below) and not the current sockets. This is essential to avoid blowing up the meter.


Set the range dial on the meter. Note that the two test leads are plugged into the appropriate sockets on the meter for voltage, and the selector switch has been set for DC “V”. The only difference in the setup of the .
