Abstract:
1. A method of processing the output signal of a measuring transducer in a force-measuring device, wherein the measuring transducer produces a measuring signal representative of a load acting on the device, said measuring signal being filtered in a variable analog filter and/or digital filter, after the signal has been processed in an analog/digital converter, in a variable digital filter, in order to remove unwanted signal components that are caused by disturbances affecting the force-measuring device, by changes in the weighing load, the measuring signal being monitored in regard to occurrence of a change in weighing load and after a load change has been detected, the method comprising: resetting and varying at least one filter parameter of the analog or digital filter as a function of time in accordance with a prescribed profile f opening the analog and/or digital filter after a load change has been detected and then closing the analog and/or digital filter to a point where a predefined filter characteristic has been attained which is determined by an end value of the at least one filter parameter.
