Apparatus for collecting vibration data in accordance with a predetermined schedule. Operable in either a data input or program mode, the apparatus is coupled with a vibration transducer which is located at predetermined coded positions and the data collected are stored in memory. Additionally, visual inspection data may be entered in the memory in the form of a numerical code along with units designations and the like. In a data input mode of operation, the apparatus operates in conjunction with a scheduling facility which offloads the schedule during a transfer mode into the apparatus at the commencement of any given maintenance round. The schedule serves to prompt the operator as to the sequence of data collection locations, additionally providing units, alarm threshold levels and like information. At the end of the scheduled rounds, the data may be offloaded to the processing facility. The apparatus includes logic which permits the analysis of the type of transducer and the requested units signal treatment as well as the automatic carrying out of alarm level comparisons.
