Abstract
A digital scale is provided that switches a measuring interval according to the amount of variation of sampled data, and computes a weight. Embodiments include a scale with pre-stored scale intervals set at multiple levels, and allowable ranges of fluctuation that correspond to the scale intervals. The scale acquires digital data of a load continuously, and computes a predetermined number, or a fluctuation range in a predetermined time, of the acquired digital data. The scale then determines the degree of variation of the digital data by comparing the computed fluctuation range with the allowable range of fluctuation stored for each scale interval, and switches the scale interval based on the determined degree of variation, thereby allowing the scale to measure and compute the weight of the load even if the fluctuation is large.
