A centrifugal balancer is combined with a computer system programed to suggest trial weights and placement and correction weights and placement to be used in interactive menu driven balancing sequences. Vibration responsive transducers provide inputs to automatic multi-gain amplifiers in a computer interface. The signals produced by the amplifiers are filtered by adjustable bandpass filters which are driven to match the rotational frequency of the work piece being balanced. Peak detectors rectify the output of the filters and an analog-to-digital converter processes the output of the peak detectors. A counter, reset by a sensor monitoring work piece rotation, is incremented until disabled by zero crossing detectors monitoring the outputs of the filters to provide relative phase information.
