This article describes new method of correction of magnetic field MPFS TWT. The method allows controlling the magnetic induction instead of the current coefficient of retarding system. This approach reduces time and increases quality of correction. The key point of the method is in controlling of magnetic field on the assembly stage. The iteration algorithm of correction was developed. It is necessary to remember the coordination of the point, which need to be corrected. After measurement the researcher will know the result of influence of correction, which he or she applies to the system. In such way all magnetic system need to be controlled. This article represents the result of this approach and shows its benefits and lacks.
