Abstract
A stabilization of the zero point of a digital display in a periodically operating weighing scale is accomplished by obtaining the difference between the then-present weight signal S and a stored reference signal, for example the tare value. Resulting differences less than a predetermined threshold value are stored. If the next following difference signal is again smaller than the threshold value and has the same sign, the reference value is corrected by the stored difference. If the signs are different, the tare or reference value remains the same and the value of the stored difference signal is changed to the newly-generated value.
