In this paper, the system designed is based on AT89C52 single-chip microcomputer to control a simple RLC tester. In order to take full advantage of single-chip computing and control functions to facilitate the realization of measurement. The parameters R, L, C converted into frequency signal f, and then use the single-chip counts obtained after the operator R, L, C values, and sent to display. The principle of conversion is the RC oscillator circuit, respectively, and three-point oscillator circuit capacitance. In order to test more accurate frequency count is the number of frequency of use of complete accuracy. Then send the results of single-chip operation, and LED display shows the measured values. Through a series of system debugging, the tester arrived at the testing standards. After testing,
