Retail weighing scale

A weighing scale, the weighing scale comprising a weighing module, the weighing module comprising:

• a housing in which a load cell is housed, the load cell comprising a fixed portion, a deformation portion, and a movable portion, the fixed portion being connected to the housing, and the movable portion bearing a spider, the housing being open upward in a region of the load cell, the spider bearing a platter, the housing being closed by the platter and by edges of the platter which protrude downward beyond the top edge of the housing, the deformation portion comprising at least one strain gauge for measuring a weight acting on the platter;
• a printed circuit board, which comprises electronics for processing a signal from the at least one strain gauge being attached to the fixed portion of the load cell, the electronics comprising a memory in which calibration-relevant data of the load cell or a value for an acceleration due to gravity are stored;
• and
• a first removable cover that is fastened to the fixed portion of the load cell by a first fastener that is secured by a calibration mark, and protects the memory of the printed circuit board against manipulation of calibration-relevant data,
• wherein:
• the load cell is fastened, by its fixed portion, to the housing of the weighing module using at least one second fastener,
• the at least one second fastener is covered by a second removable cover, and
• the at least one second fastener is configured to be accessible from outside the housing and able to be released only in a state where the second removable cover is removed.
