Abstract
Apparatus for carrying out the field balancing of rotors utilizing trial weight techniques. A display is provided with the portable apparatus which serves to prompt the operator with respect to proper procedures for 1 and 2-plane balancing. The apparatus further incorporates a non-volatile random access memory in which balancing parameters for a number of rotors may be permanently stored for use in subsequent trim balancing procedures. This same non-volatile memory is utilized additionally for the storage of null and gain categorized calibration data. A synchronous form of filter is provided for balancing which additionally is used for the purpose of aiding the operator in carrying out vibrational analysis in the field.
