AC parameters measuring system of nonlinear resistances, which can adjust AC power source automatically, is developed, based on function generator MAX038, general multiplication AD734, data collecting card and computer with A/D and D/A port. The system can be used to measure AC parameters of nonlinear resistances, i.e. U1mA ,U100μA, U10μA and Io（total leak current）, L （resistive current）. The AC voltage output range from 0 V to 15 kV, and the harmonic value is less than 1.5%. Adopting the harmonic compensative technique, L can be measured, and compared with Heithleyl91 of high accuracy （0.1%）, the measuring deviation is less than 1%. Therefore, this measuring system has higher efficiency and precision.
