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 ṽ. 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.

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 .
