A weighing scale has a measuring platform which is supported by at least three supporting feet resting on a floor, wherein to each supporting foot a load cell is assigned, wherein each load cell senses the share of the weight force originating from the measuring platform supported by the respective supporting foot. Each supporting foot is designed as a vertically extending measuring foot and comprises a load cell carrier on which the load cell rests and is attached, and an adjusting foot located below the load cell carrier. The load cell carrier is screwed with its external thread into the internal thread of the adjusting foot such that, by turning the adjusting foot relative to the load cell carrier, a vertical height of the measuring foot along a vertical screw axis is adjustable.

A digital filter for a digital weigher reduces a calculation time in an adapted filter while maintaining weighing accuracy, a digital weigher includes the filter for the weigher, and a wave filtering process method uses the digital filter for the digital weigher. A fixation section of a FIR filter removes an oscillating component in a predetermined frequency range, from a digital weighing signal. A determination device determines whether an amplitude of an oscillating component contained in a digital weighing signal derived by performing a wave filtering process falls within a predetermined damping range. A control device changes a frequency range of an oscillating component to be removed by an adaptive section of the filter based on a result of the determination. The adaptive section of the filter performs the wave filtering process with respect to the oscillating component in the frequency range changed by the control device.
