Abstract
A force measuring device, especially a weighing device, has at least one force-measuring module that includes a force-measuring cell, a communication means, a terminal and at least one communication line, through which communication signals are transmitted between the terminal and the communication means. In a method for determining the condition of such a device, at least one voltage present at the communication line or at the communication means is measured. The measured value, or a processed result therefrom, are transmitted through the communication line to the terminal. A parameter representing the condition of the force-measuring device is determined from the measurement value, or the processed result, in an accurate and simple manner.
