ABSTRACT:
A balance with a wind guard moved by a motor whereby the position of movable walls of the guard are monitored by a sensor. An electronic memory is provided for the desired end position of the movable wall elements. The desired end position of the removable walls can be stored in this memory in a learning phase and when the walls are opened by the motor, they are opened only up to a preselected position. This minimizes the time for opening and closing the weighing area and diminishes exposure to air turbulence within the weighing area.
