ABSTRACT OF THE DISCLOSURE An efficiency monitoring device determines the efficiency of a machine and operator where the machine is turned off and on by the operator. Efficiency is determined by first monitoring the cycle speed of a machine by means of a light source, a reflective tape, and a photoelectric cell which produces a signal from which a digital computer can continuously calculate the instantaneous cycle speed. The computer maintains a continuous time base, and then plots the cycle speed as a function of time to produce an efficiency profile for the machine and operator.
