An arrangement on an electrical weighing balance for the digital display of weighing results. The balance has an output voltage analogous to the load. An analogue-digital converter having several digit display units is connected to the output of the balance. There is an additional digit display unit and a voltage compensating circuit and an amplifier with selectable amplifying factors of 10 and 1 which can be switched in between the output of the balance and the input of the ADC, and voltages from 0 to 9/10 of their input voltages are selectively adjustable in stages of respectively one-tenth on the voltage compensating circuit, whereby initially the output voltage of the balance is fed to the ADC, bypassing the compensating circuit and with an amplifying factor 1 of the amplifier, the highest place displayed digit can then be adjusted on the additional DDU, a compensating voltage of which can be adjusted on the compensating circuit and the amplifier can be changed over to the amplifying factor 10. The additional unit may be replaced by two additional units and the amplifier will have an amplifying factor of 100.
