Abstract

The present invention is a method and apparatus for determining whether the sensors or the used in a device monitoring system are properly functioning before rendering a determination as to a defect within the device itself. As a result, maintenance costs may be reduced while limiting the number of false indications of failure, thereby increasing the reliability of the monitoring system.
