    Abstract: A process, such as for instance the operation of a machine, is automatically supervised by monitoring at least two of the operational parameters which are desired to have a prescribed relationship to each other. A curve is formed which graphically represents the actual monitored relationship of the parameters, and it is compared to a standard curve representing the desired relationship of the parameters. In the event of a deviation between the curves, a signal is produced to indicate such deviation. An apparatus for carrying out the method is also disclosed.
