A diagnostic tool may be attached to the control panel of a piece of machinery within a plant or factory which includes an electric motor. The diagnostic tool includes indicators for providing information to an operator of the equipment for which the control panel provides power. These indicator inform the operator of various modes of operation of the control circuitry within the control panel which regulate the power going to the motor. In this manner, the operator may determine if the machinery is ready to run, and if not, if it is necessary to call a technician.
