Abstract：
In the BEPCⅡ, a great deal of DCCTs, with current output, are used as the measuring and feed-back units in power supplies. High Precision Standard Testing System for DCCT is designed and developed in order to detect and adjust the capability of DCCT. This testing system mainly consists of a PC computer, a 7.5 Digit Multimeter, a high precision DC current measuring system, and a high precision and stability power supply. The function and the structure of the testing system are simply analysed, and the test data are presented.
