This paper introduces the basic principle, instrument structures and electronics measurement system of the electron polarimeter developed successfully by our laboratory. Based on the PC data acquisition and processing system, the whole experiment process can be controlled and achieved automatically. As a test for the electron polarimeter and its electronics measurement system, the relative Stokes parameters of linear polarized weak light are determined. The results show that the whole instrument system has the advantages of high precision, compact structures and stable performances.
