Abstract
An electronic scale (1) with a display unit (9), at least one control button (11 . . . 14), a digital signal processing unit (5) and a digital interface (7) to a higher-level electronic data processing (EDP) system (15). The digital signal processing unit (5) has an activatable switch or program part for locking the scale. This switch or part releases the display of the weighing result only for as long as the higher-level EDP system (15) communicates with the scale (1) and locks the display at other times. The activation of the switch or part for the locking process is stored in a power-failure-proof memory (21).
