This paper introduces the test module which adopted Atmega168 as the core controller, keyboard controller BC7281B as the test input and display devices. AVR single-chip computer scanning the keyboard to read the input and the test range and displays them. When finished settings, connecting the product to the power, the module will start test procedure automatically. After finishing the first test step, the module indicates to inform the tester to start the second step. After finished all the test step, the test module gives the result to the tester whether the product is qualified or not. The practical application shows that the measurement and control system has high measurement precision and high reliability.
