Abstract:
1. A method for determining the condition of a weighing device with at least one force-measuring module comprising a force-measuring cell and a communication means, with a terminal and with at least one communication line through which communication signals are transmitted between the communication means and the terminal, comprising the steps of: measuring at least once the electrical voltage of the at least one communication line, using a voltage sensor, during a measurement time interval that is set aside during operation of the weighing device, by interrupting communication over the at least one communication line between the communication means and the respective terminal or communication means of the further force-measuring module; generating a measurement value from the measured voltage, and, optionally, generating a processed result from the measurement value; transmitting, by way of the at least one communication line, a measurement signal, comprising the measurement value and, if applicable, the processed result thereof; and determining, at a receiver, a parameter representing the condition of the force-measuring device, based upon the measurement signal, the receiver being at least one of: the terminal and the communication means of a further force-measuring module.
