Abstract: In a system for predictive maintenance of machinery based on vibration data history, a portable battery operated vibration data collector and processor unit (10) is equipped with an electro-optical wand (18) for reading a bar code affixed to each data collection station (22) on the machinery that is to be tested. The vibration of the machinery is sensed by electro-mechanical transducers (16) temporarily attached by an operator to permanent indexing mounts (24) at each test station. The bar code (26) identifies the station and automatically initiates a predetermined sequence of vibration data collection, processing and data storage operations.
