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