ABSTRACT:
An electronic scale having a measuring sensor (1 . . . 16), a digital signal processing unit (18), a digital display (19), a bubble level (20), which includes a container (21) that is partially filled with a liquid (22) while forming a gas bubble (23), and circuit component or program routine in the digital signal processing unit (18) for detecting a displacement of the gas bubble (23). An additional circuit component or program routine detects the diameter of the gas bubble (23). The diameter of the gas bubble changes due to vertical vibrations of the scale. The signal from the measuring sensor (1 . . . 16) falsified by vibrations can thus be corrected by the digital signal processing unit (18) by calculation, making use of the diameter signal.
