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.

Field balancing apparatus

Electronic balancing apparatus for rotating bodies in which unbalance read-out for two-plane dynamic balancing can be obtained on an initial run without the need for trial weights or calibration runs, and wherein manual filter tuning, manual ranging of amount displays and manual entry of right and left calibration weights are eliminated. In addition, the system will automatically divide correction weights between two points on a rotor, will combine multiple corrections into one weight, and incorporates memory meters which hold their readings from run-to-run without adjustment.
