CIRCUIT ARRANGEMENT AND METHOD FOR CALIBRATION OF A SENSOR ARRANGEMENT IN PARTICULAR FOR MOTOR-ADJUSTED FURNITURE AND MEASUREMENT AMPLIFIER AND SENSOR ARRANGEMENT

摘要

The invention relates to a circuit arrangement, in particular for motor-adjusted furniture, comprising a signal processing device (3) for processing a sensor signal (7) and a calibration device (2, 3, 4), which trims the signal processing device to a given value at a given time by means of a control signal (10). A control signal is generated for the method for calibration of a sensor arrangement which activates a calibration device generating a calibration signal which may be trimmed with a sensor signal. The invention further relates to a corresponding measurement amplifier and corresponding sensor arrangement.
