Abstract
A combination weighing machine has a plurality of weigh scales which provide signals representative of the weight of product in each scale. A search control receives the weight signals and selects a combination of the scales which together compose a charge of the product equal to or closely approximating a given target weight. Transient errors existing in the weight signals at high speeds of operation are corrected by means of adjustment parameters that are periodically recalculated on the basis of known differences between settled and unsettled weight signals.
