A force-measuring device (100) with at least one housing (20) has an interior space and at least one force-measuring cell (110) installed therein. At least one parameter characterizing an existing high-frequency electromagnetic field is determined by a sensor (50) arranged in the interior space or a sensor arranged outside of the housing, the sensor being adapted for detecting high-frequency electromagnetic fields. After an electromagnetic field is detected and compared to a threshold value, a response action of the force-measuring device is triggered if the detected parameter value exceeds the threshold value.
