Abstract
A method for taring a dosing belt weigher uses a weight signal produced by a load cell and a belt revolution signal produced by a sensor for providing a taring or weight correction signal that is processed in a taring unit. The taring unit ascertains the weight or load signal individually for each belt section and for a statistically relevant number of belt revolutions. Individual mean values are formed for the individual belt sections and these individual mean values are compared with the total mean value of the ascertained gross weight signals. The resulting difference values are used as taring signals for correcting the individual belt influences which are correlated locally to each individual belt section during the following belt revolution. Thus, each belt revolution is corrected with due regard to the values gathered in a substantial number of preceding belt revolutions.
