Electronic scale and method for weight measurement including correction means for correcting a weight dependent signal

Abstract

A scale having an electronic weighing system to generate a weight-dependent signal and a digital signal processing unit (18). The digital signal processing unit (18) has a circuit or program parts which measure the time elapsed since connection of the voltage to the scale. To dramatically reduce the time required for the scale to reach its full accuracy after connection of the voltage supply, the digital signal processing unit (18) has computation modules (34, 35) that correct the weight-dependent signal generated by the weighing system by a correction value that depends on the time elapsed. The magnitude of this correction value, starting from an initial correction value, converges with increasing time elapsed to a constant end value that differs from the initial correction value.
