Abstract:
A method, and a device that is operable according to the method, for monitoring the condition of a force-measuring device, particularly a weighing device having a movable force-transmitting portion through which a force that is acting on the force-measuring device is transmitted to a measurement transducer that generates a measurement signal corresponding to the applied force, whereupon the signal is brought into the form of a display indication or passed along for further processing. In the method and device of the invention, at least one parameter is determined, which parameter characterizes the free mobility of the force-transmitting portion, or a change in the free mobility of the force-transmitting portion over time. The parameter is then compared to at least one threshold value, and based on the result of the comparison an action of the force-measuring device may be triggered.
