摘要：
A method and an apparatus for dynamically check weighing objects (18a-c) that are guided across a weight-sensitive zone (14) of a weighing device (12) by a conveying mechanism (20a-c). At regular intervals, the weight-sensitive zone (14) supplies individual measured weight values (E1, . . . , En) from which resulting weight values are derived in a digital evaluation unit (16) by calculating mean values. The evaluation unit (16) includes a plurality of cascading mean value filters (24a-e) that have different filter lengths which are varied by a common scaling value in accordance with a spatial dimension of the objects (18a-c).
