To improve the performance of the Hefei Light Source (HLS), in particular to get higher brilliance synchrotron radiation and increase the number of straight section insertion devices, NSRL is now upgrading HLS to HLS II. Most of the magnets had to be replaced in this project. To measure the magnets, set of the magnetic measurement equipment in NSRL are also re-built. New magnets are sample measured, the discreteness and uniformity of integrated magnetic field all meet the requirements. Piecewise fitting and electron tracking of bending magnets for injector and beam transport line were performed and the results showed that the electron trajectory fitted the physical design well.
