A position-measuring device for detecting the relative position of two bodies capable of motion relative to each other includes a measurement standard with a scale division connected to one of the bodies and a scanning head (MK) connected to the other body for reading the scale division, wherein the scanning head is connected to an electronic evaluation unit. The electronic evaluation unit has a nonvolatile memory in which correction values for the measurement values recorded by the scanning head are stored, wherein the correction values are determined during a preceding calibration of the position-measuring device together with the use of at least one other scanning head to scan the same measurement standard.
