Abstract
Analog signals are generated in response to one or more operating parameters of a machine such as vibration and used to provide a log of the operating history of the machine. The analog signals are converted into root mean square (rms) values which are periodically sampled. The sampled signals are sorted into predefined rms value bands. Each occurrence of a signal in an rms value band is used to increment a counter in order to keep track of the number of occurrences of signals in a particular rms value band. The number of accumulated signals in each of the rms value bands provides an indication of the usage and condition of the machine.
