Abstract：
The new DCCT measurement system is developed for Hefei Light Source (HLS). The system is composed a PCT system, a DCCT shielding system and a DCCT data acquisition system. The magnetic shielding against stray fields suppressed zero drifts of DCCT from 1mA to 10μA. In new DCCT measurement system, the resolution is about 1μA rms, the accuracy is about 0.1%.
