Therefore, the design is reliable, safe, and convenient electronic components tester has a great practical necessity. In the hardware design of the system to ATmega 8 microcontroller as the core of the electronic component tester, the shock current charge and discharge the measurement of various parameters on the measured components. The system passed the test circuit, the signal input, take the average and other technology to get better test results. Able to complete these basic electronic components resistor capacitor test, but also most of the semiconductor device parameters of the test. The paper detailed the basic principles of the system, the hardware framework, the main circuit and software framework. On the subject of research helps to understand the performance of the various parameters of the electronic components and electronic components. In the large-scale equipment design practice, the measurement of electronic components is an important direction of development.
