Thanks everyone,
one last question which I still do not have clarified is whether the scale is measuring the restoring force or the actual force of the weight.
It must be both or neither: because they come in pairs, it can't be one or the other. But whether it is both or neither is a choice I leave to you. To explain what the scale actually does: the scale has sensors (as turbo suggested) that directly measure the movement (strain) of the spring. The scale then calculates the force required to cause that amount of movement.
