  The system of beam correction for European XFEL includes about 400 precise current sources. Before including in XFEL equipment the every current source must tested and verified in concordance with specifications. For this purpose there was developed the automated system allowing to test up to 7 current sources simultaneously. The system consists of stand and software that written for linux OS. The stand was equipped by test loads, which emulated the real load, by precise DCCT and by precise analog-to-digital converters with CANbus interface. During testing the current in each current source was changed and digitized in concordance with different algorithms. The duration of typical session was 25 hours. The specific software was developed for this stand. It provides testing process, collecting and storing the primary information and displaying the first information. There are addition utilities which allows to make different analyzes in off-line mode using data accumulated during tests. The article provides a detailed description of the stand and main results.
