When performing an inspection, I will use a receptacle tester similar to the one pictured. The tester is used to test a representative number of receptacles for specific deficiencies. The most common deficiency found is an open ground.
The purpose of an electrical ground is to provide an exit path for electricity so if there is a malfunction with your electrical outlet or appliance, the electricity will enter the earth, instead of people or equipment that are in contact with the malfunctioning outlet. An open ground prevents this from happening, causing a dangerous situation.
An open ground is usually caused by a loose, broken, or damaged ground wire. If the wiring is in good shape and properly installed, an open ground reading on the tester could also be caused by a bad receptacle. In this case, the receptacle should be replaced immediately.
