To obtain an indication of 0.000 kg in spite of small deviations of the measuring bridge loading of the scales from the tare weight, for example due to position changes, vibrations, weighing remainders and so forth, a differentiating unit (7) is provided by means of which the counts of the counter (4) are monitored and which, up to a particular deviation of the counting mechanism from the value corresponding to the zero indication outputs a correction command to a correction unit (5). The correction unit (5) in turn sets the counter (4) in such a manner that the said deviation disappears and accurate zero is indicated. <IMAGE> |
