Abstract
A method for operating a magnetostrictive displacement measuring device, having a wave guide for guiding at least one mechanical wave, at least one damping zone, a magnetic position encoder which is displaceably arranged along a measuring range of the position measuring device and a detection unit, generates the at least one mechanical wave by an excitation signal (IP) having a clock frequency (f, f), at least two mechanical waves having respectively different clock frequencies (f, f, f) being generated. The clock frequencies can be predetermined such that interfering reflections (R, R) occur at different positions (x, x, x) of the measuring range of the displacement measurement device, and during the method of the position encoder, switching between the different clock frequencies (f, f, f) takes place, such that the interfering reflections (R, R) on the respective different positions (x, x, x) of the measuring range are masked out.
