Abstract
A linear position measuring system and a method for determining an absolute position of a carriage along a slide rail are disclosed. An analog signal progression (S) based at on at least one reference point is here discretely scanned in response to a first threshold (SW) and second threshold (SW). The resultant digital values are stored in a first measured value register (MR) and a second measured value register (MR). The contents of the first and second measured value register (MR, MR) are compared with the respective contents of a first and second set measured value register. The reference point is output as an ideal reference point if the differential value lies within a predetermined tolerance range, and is otherwise discarded.
