| 1. A digital scale which computes a weight value based on a predetermined scale interval, the scale comprising:
data acquiring means,
computation means,
storage means,
judging means,
scale interval switching means, and
display means;
wherein
the data acquiring means acquires digital data of a load continuously,
the computation means computes a predetermined number or a fluctuation range in a predetermined time of the acquired digital
data,
the storage means stores a plurality of scale intervals set at multiple levels and allowable ranges of the fluctuation range
that correspond to the scale intervals,
the judging means determines the degree of variation of the digital data by comparing the computed fluctuation range with
the allowable range of the fluctuation range which is stored for each scale interval,
the scale interval switching means switches the scale interval to one scale interval selected from the plurality of scale
intervals based on the determined degree of variation,
the computation means computes a body weight value from the acquired digital data based on the selected scale interval switched
by the scale interval switching means, and
the display means displays the body weight value and the scale interval.
