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.
Electronic balance comprising a measured value receiver and an electronic evaluation unit having a digital and an analog display, whereby both displays are controlled by the electronic evaluation unit, a digital input means is used for inputting a set weight for a loading procedure, the balance is characterized in that the electronic evaluation unit (14) contains a memory (15) for storing the set weight of the loading and an arithmetic unit (16) permits the values displayed 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 the loading procedure the digital display runs from a negative set weight to zero and the analog display runs from 0% to 100% of the set weight, the analog display (6, 6') comprises adjacent bars (7, 7', 7a, 7b, 7c) which can be shifted in their lightness, whereby the length of the individual bars decreases continuously from 0% towards a 100% point and over 100% increases continuously again.
