AbstractIn a dynamic weighing device including a weight signal treating filter for measuring the weight of an article while the article is conveyed by a weighing conveyer, a device and a method of automatically determining an optimum time point for reading the weight signal and/or an optimum characteristic of the filter to be used, wherein the weight signal is read and stored plural times between two predetermined time points with and/or without variation of the filter characteristic, this operation is repeated about the same article or a plurality of articles which are substantially same in weight and, thereafter, the reading time point and filter characteristic corresponding to one of the groups of weight measurements of the respective times which gives a minimum dispersion of the weight measurements are selected as the optimum conditions.
