Pitch measuring device and method for checking an adjustment precision of a component moving on a motion path

A method comprising the steps:

• moving a machine element of a machine along a movement path that is at least two dimensional, and
• checking a positioning precision of the machine element by a pitch measuring device, the pitch measuring device including:
• a housing including
• attachment devices for attachment of the housing at the machine element,
• an integrated measuring device which includes a centrally arranged rotation shaft and a rotary encoder in the housing for detecting an angular position of the rotary encoder relative to the rotation axle,
• wherein the housing is arranged at the machine element performing the movement path with the horizontal rotation shaft,
• wherein a first inclination sensor is arranged at the housing and a second inclination sensor is arranged at a frame element of the machine and data provided by the first inclination sensor and the second inclination sensor during a position change of the machine is computed with data determined by the rotary encoder.
