PROBLEM TO BE SOLVED: To facilitate a setting operation of boundary weight value for a rank sorting of an object to be weighed into a plurality of weight ranks.SOLUTION: When an object to be weighed is rank sorted into a plurality of weight ranks, by inputted a kind of the object to be weighed and the number of ranks of the weight ranks, and based on upper and lower limit weight value of the kind of the object to be weighed and the number of ranks, a boundary weight value is calculated so that the weight width of each of a plurality of weight ranks is equal and set up automatically. |
