Patent ID: 7516035

Claim:
A method for correction of drift phenomena in an electronic force-measuring device that includes a measuring transducer, the method comprising: receiving a measuring signal from the measuring transducer, said measuring signal representing a load applied to the force-measuring device, said measuring signal being received by a signal-processing unit that is supported by at least one processor and serves to process digital signals, and said signal-processing unit being adapted to compensate for drift deviations; calculating a time-dependent correction value by which the drift error of the measuring signal is corrected based on stored drift parameters accessed by the processor from a computer-readable memory unit, the processor and the signal-processing unit being under the control of an optimization program that is stored in the memory unit, wherein: at time intervals that are either controlled automatically or chosen by the user, new optimized values for the drift parameters are automatically determined from at least one uncorrected or only partially corrected amplitude profile that was stored previously or at the current time, from a corresponding amplitude/time value pair of the measuring signal, or from a signal profile; and said new optimized values for the drift parameters are stored in the memory unit.
