Abstract

An electronic balance for dosing, with a measured value receiver, a digital signal processing unit, a digital entry keyboard for entering the theoretical value of a dosing, with a theoretical-weight memory and with a digital display unit with several positions after the decimal point, that switching means are present which determine the highest-value decade in which a number in the display is not equal to zero and that these switching means regulate the decoding of the display in such a manner that all zeros to the left of this decade up to the units decade are represented as a small zero "o" whereas prezeros in the 10 decade, 100 decade, etc. are entirely suppressed in a known manner. This makes possible a quasi-analog representation of the measured value which is attained in the units decade, the 10 decade, the 100 decade, etc. by means of the known suppression of prezeros even in the case of balance displays with positions after the decimal point.
