Abstract

A balance with a wind guard moved by a motor whereby the position of the moveable walls of the guard are monitored by a sensor. An electronic memory is provided for the desired end position of the moveable wall element. 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. This intuitively and flexibly assigns wall elements to user keys.
