A method serves to correct drift phenomena, in particular creep effects, occurring in an electronic balance that has a measuring transducer through which a measuring signal is formed which is representative of a load applied to the force-measuring device. The measuring signal is delivered by way of an analog/digital converter to a signal-processing unit that is supported by at least one processor, said signal-processing unit being capable of compensating drift deviations, for which purpose the signal-processing unit, via the processor, accesses drift parameters that are stored in a memory unit and serve as basis for calculating a time-dependent correction value by which the drift error of the measuring signal (ms) is corrected. At time intervals that are either controlled automatically or chosen by the user, new optimized values for the drift parameters are determined automatically by the processor and the signal-processing unit under the control of an optimization program that is stored in the memory unit, and the new optimized values are filed in the memory unit.
