  • Patent number: 6674019
    Abstract: A display and operating element (1) for an electronic scale with a display area (2, 3) in which the weighing results and values, parameters or selection lists can be displayed for user prompting either separated spatially or in succession over time, and having at least one button (6-8) for operating the scale. The display and operating element (1) has a rotary knob (4) on one side that turns in both directions to cause the values, parameters or marked areas of the selection list displayed in the display area (3) to change in one or the other direction. A button (5) is assigned to the rotary knob (4) as an acknowledgement button. Operation of this acknowledgement button (5) causes the value, parameter and marked area of the selection list selected using the rotary knob (4) to be accepted into the electronic evaluation unit of the scale. Accordingly, simple and fast setting of values and/or parameters and a fast selection of a specific item from a selection list can be achieved.
