Abstract
Abstract 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.
