Weighing device with a wheatstone bridge assembly and method

A weighing device for an electronic bathroom scale comprising four feet, including respectively a left front foot, a right front foot, a left rear foot, and a right rear foot, the left front foot comprising a left front load cell, the right front foot comprising a right front load cell, the left rear foot comprising a left rear load cell, and the right rear foot comprising a right rear load cell,

• each load cell of the left front, right front, left rear and right rear load cells comprising at least two resistors,
• the left front, right front, left rear and right rear load cells being combined in a Wheatstone bridge assembly comprising:
• a first branch and a second branch, the first and second branches being mounted in parallel between a reference voltage and a ground potential, the first and second branches being arranged on either side of a first axis of symmetry passing through the reference voltage and the ground potential;
• a first intermediate point, on the first branch, and a second intermediate point, on the second branch, the first and second branches comprising a same number of resistors on either side of the first and second intermediate points, respectively, so as to define a second axis of symmetry passing through the first and second intermediate points;
• and
• a first auxiliary circuit, configured to selectively short-circuit two resistors (a) belonging to a same load cell of a first foot of the four feet in the weighing device so as to short-circuit only said load cell of the first foot in said Wheatstone bridge assembly or (b) belonging to two neighboring load cells of two neighboring first feet of the four feet in the weighing device so as to short-circuit only part of the at least two resistors of each of said two neighboring cells in said Wheatstone bridge assembly, the first auxiliary circuit being symmetrical relative to the first axis or the second axis,
• the assembly being controlled by an electronic control unit.
