ABSTRACT:
The invention discloses an electronic balance comprising a measured value receiver (23) and an electronic evaluation unit (14) having a digital display (10) and an analog display (6), whereby both displays are controlled by the electronic evaluation unit (14). A digital input keyboard (12) is used for inputting the set weight value of a loading. The electronic evaluation unit (14) contains a memory (15) and an arithmetic unit (16) which permit the values indicated in the digital display (10) and in the analog display (6) to be differentiated against each other by the amount stored in the memory (15) so that during a loading procedure the digital display (10) runs from the negative set weight value to 0g and the analog display (6) from 0% to 100%. The analog display (6) consists of adjacent bars (7) which can be shited in their lightness, whereby the length of the individual bars continuously decreases from 0% to 100% of the set weight value, and continuously increases again over 100% of the set weight value.
