How do you check the voltage of an electrical outlet?

Using the same hand, insert a probe into each vertical slot on the outlet. Red goes in the smaller slot, black into the larger one. A properly functioning outlet will give a reading of 110-120 volts. If there is no reading, check the wiring on the outlet.
