A method for configuring a field device for use in custody transfer and such a field device, wherein the field device has a computing unit and a storage, wherein parameters and/or functions are stored in the storage, and wherein the parameters and/or functions are at least partially configurable. A more flexible configuration of the field device used for custody transfer is achieved by at least two blocking groups being provided, wherein each blocking group comprises at least one parameter and/or at least one function of the field device, at least one blocking group is chosen and evaluated by the computing unit, and the computing unit blocking the parameters and/or functions contained in the chosen at least one blocking group against a subsequent change.

A commercial-transaction weighing instrument (110) subject to W&M legal controls, configured with a weighing platform (12), at least one load cell (16), a controller (120) with weight-processing (122) and communications (124) modules, and software to be implemented on a general-purpose computer with display and data entry capabilities. The general-purpose computer itself is not subject to legal controls. The weight-processing module receives data from the at least one load cell and generates output data in the nature of weight and legally-required weighment information. The communications module receives the output data of the weight-processing module and further transmits the data to a general-purpose computer (136). Software implemented on the general-purpose computer has program code for establishing encrypted bidirectional communication with the communications module and to operate as the primary display device for the weighing instrument. Software implemented on the general-purpose computer also has program code for transmitting signals from the general-purpose computer to the communications module in the nature of data or instructions for the weight processing module.

The present invention relates to a load cell for a scale having a monolithically configured measurement body that has a force reception section, a force introduction section, and a joint section arranged between the force reception section and the force introduction section, having at least one strain gauge arranged at the upper side on the joint section for detecting a stretching deformation of the measurement body, and having electronics that are arranged at the force reception side, that are at least partly arranged on a circuit board, and that have a memory in which calibration data of the load cell and/or a value for gravity are stored, wherein a hardware interface is provided via which the memory can be accessed and via which the calibration data stored in the memory and/or the value for gravity can be changed.

The invention relates to a method for displaying the weighing result of a scale, in particular a shop scale, which comprises an identification, on a mobile display device. In said method, the mobile display device establishes a secure wireless communication link to the scale and displays the identification of the scale once the link has been successfully established.
