Abstract
To achieve an automatic stabilization of the zero point in a scale having a digital display, any difference between the load proportional signal and the stored reference signal (for example, the tare value) is compared to a threshold value. Differences which are less than the threshold value are halved in a divider. The halved difference signal is then used when the next subsequent one of the load proportional signal is compared to the reference signal, preferably by algebraic addition of the halved difference signal to the reference signal.
