Method for one of adjusting (taring) or re-calibrating an apparatus that includes a liquid-filled previously pressurized flexible tube that is closed at one end and is connected to a pressure sensor at an other end. Method includes activating predetermined controlling functions by establishing a differential of an external pressure exerted onto the tube by a person and a pressure prevailing in the previously pressurized tube. In establishing the differential, the method includes taking into account variations of the pressure prevailing in the previously pressurized tube, when no external pressure is being exerted on the tube by the person, due to at least one variable external ambient parameter.
