Process for compensating tolerances of the position signal (14) of a position transmitter (10, 13) characterized by two limit stops (11, 12). In order to adapt the first and second end values (W1, W2) of the position signal (14) which are allocated to the two limit stops (11, 12), two start values (W1S, W2S) stored in a constant-storage memory (16) of the evaluation circuit (15) are taken as a basis, said values both lying inside the travel covered by the position transmitter (10, 13). The two start values (W1S, W2S) are then transferred to a write/read memory (17) as end values (W1, W2) and cyclically compared with the position signal detected (14). If a memorized value (W1, W2) is exceeded, the signal (14) detected is passed to the write/read memory (17) as the new end-value (W1, W2) and the previous value deleted. The position signal (14) is related to a reference value determined from the two end values (W1, W2) and converted into a normalized output signal (18) and then issued as the output.
