PROBLEM TO BE SOLVED: To allow a quantitative measurement to be efficiently performed by simple operation without depending on human experience and intuition.SOLUTION: Objects to be weighed are measured by an electronic balance 10 and thereby housing positions classified by ranks corresponding to weight ranks to which the objects to be weighed belongs are indicated by display units 20a to 20n. Accordingly, the object to be weighed are housed in the housing positions classified by ranks according to the indication to perform rank classification work, and the objects to be weighed of the corresponding housing positions classified by ranks are extracted and combined according to the combination of a plurality of housing positions classified by ranks indicated by the display units 20a to 20n. Thereby, the combination of the object to be weighed which becomes a target weight is completed. |
