description The present invention relates to a process and a device for adjusting a deflection unit without utilizing a test tube whereby a measuring head is employed that samples the field along the length of the axis of the deflection unit in at least two zones, and the signals issuing from the measuring head represent the fields generated by the line and raster windings. These signals are connected to a computer that simulates the mechanical adjusting operations such that the error signal supplied to a servo-device may control the displacement motors of the raster with respect to the center line of the deflection unit.
