PURPOSE:To reliably notify a weight value being displaced outside a scale range, by a method wherein, a case in weight value is displaced outside a preset scale range, an indicating element is lighted in a cyclic scanning manner. CONSTITUTION:A microprcessor 32 reads count data from a A/D converter 29 based on program data set in a built-in ROM, and compute using an operational register formed in a RAM to find a weight value. In case the computed weight value is within a scale range, a weight assigning lamp to be lighted is designated, and a lamp assigning signal is supplied to an indicator 56. In case the computed weight value is displaced outside a preset scale range, a signal, which lights lamps in turn in a cyclic scanning manner, is fed to the indicator 56. |
