The possible deflection of the electron beam, introduced by undulator, must be corrected by means of two air coils. These air coils, which are installed from both sides of the undulator, must eliminate not only the deflection angle, but also the displacement between electron beam trajectory and the orbit. For European XFEL 182 air coils are necessary. To minimize the measurement time an automated procedure has been developed and implemented. This paper describes the measurement setup, technical implementation method and automation procedure.
