The invention relates to a method for determining the state of a force measuring device (200), particularly a weighing device, and to a suitable force measuring device comprising at least one force measuring module (244) having a load cell (210) and a communication means (248), and further comprising a terminal (206) and at least one communication line (212), via which communication signals (c) can be transmitted between the terminal (206) and the communication means (248). According to the invention, at least one electric potential (Vs) present on the communication line (212) and/or on the communication means (248) is measured, the at least one measurement value (M) and/or the processed results (R) thereof are transmitted via the at least one communication line (212) to the terminal (206), and from this a parameter of the state of the force measuring device (200) is determined. In this way, a state determination is achieved in a precise and simple manner.
L'invention concerne un procédé pour déterminer l'état d'un dispositif dynamométrique (200), notamment d'un dispositif de pesée, ainsi qu'un dispositif dynamométrique approprié comprenant au moins un module dynamométrique (244) présentant une cellule dynamométrique (210) et un moyen de communication (248), un terminal (206) et au moins une ligne de communication (212) pour la transmission de signaux de communication (c) entre le terminal (206) et le moyen de communication (248). Selon l'invention, au moins une tension électrique (Vs) sur la ligne de communication (212) et/ou sur le moyen de communication (248) est mésurée; au moins une valeur de mesure (M) et/ou ses résultats traités (R) sont transmis au terminal (206) par l'intermédiaire de la ou des lignes de communication (212), et un paramètre de l'état du dispositif dynamométrique (200) est ainsi déterminé. On obtient ainsi de manière simple et précise une détermination de l'état.
