摘要: In known scales, switching from a fine to a course measurement range automatically decreases the resolution by at least one place. Since the change in range takes place in dependence upon the total weight applied to the scale, displayed values after taring still lack at least one significant digit relative to the fine indication. In the present invention this digit is reactivated automatically upon activation of the tare key if the weight after taring is less than the predetermined fine range limiting weight.
