ABSTRACT:
Method and scale are designed for the manual or automatic weighing of objects of the same nominal weight by means of a scale locked over its measuring system, having a computing device for establishing the weight of the goods to be weighed from the digital output signals of mechanical-electrical converters, e.g. from pre-tensioned measuring strings loaded by the weight of said goods, in which if the load on the measuring system is lower or higher than predetermined limits of the load corresponding to said nominal weight, an electromagnetically generated force acts upon the load support of the scale and prevents the overshooting of said pre-determined load limits.
