ABSTRACT:
The invention relates to a digital scale, in which an analog output signal of a weighing cell is converted in an analog/digital converter into a digital signal. The digital signal is applied to a microprocessor, which compares it with a zero value, derives the weight to be displayed from the comparison and causes it to be displayed in a display device. At regular time intervals, a clock transducer turns the weighing cel on and stores the thus received output signal of the weighing cell in memory in alternation. The output signal most recently ascertained and stored memory is compared with the stored output signal ascertained one time interval previously and, and if the difference exceeds a predetermined threshold is displayed in the display device.
