1. Apparatus for balancing an identifiable rotor utilizing vibration responsive transducer means having vibration responsive output signals, rotation transducer means providing rotation responsive signals correspoding with a reference location of said rotor, and select utilization of a tral balance weight removably connectable with said rotor comprising:

  • means for receiving said vibration responsive output signals;

    means for receiving said rotation responsive signals;

    analyzer nework means responsive to said vibration responsive output signals and to said rotation responsive signals, and including means defining a filter synchronous with respect to said rotation responsive signals for deriving vector categorized signals corresponding with amplitudes and phase of vibration with respect to said reference location;

    hold switch means for selectively deriving a data accept condition;

    function switching means actuable to effect a balance condition;

    memory switching means actuable to effect store and recall conditions;

    display means for providing a visible readout of information;

    a random access memory;

    non-volatile random access memory means for retaining balance parameter data at discrete identifiable locations in the absence of applied electrical power;

    processor means responsive to first said vector categorized signals derived from an initial rotation of said rotor when said function switching means is in said balance condition and said hold switch means is in said data accept condition for effecting the submittal of said first signals to said random access memory, responsive to second said vector categorized signals derived from a next rotation of said rotor with said trial balance weight connected therewith when said function switching means is in said balance condition and said hold switch means is in said data accept condition for effecting the submittal of said second signals to said random access memory, for computing balance correction parameters with respect to said first and second signals, for effecting the readout of balance correction information corresponding therewith at said display means, and subsequently responsive to actuation of said memory switching means to said store condition for effecting the storage of said computed balance correction parameters in said nonvolatile memory means.
