【Abstract】 Aiming at the problems existing in the traditional resistance tester, a domestic small reinforced resistance tester is designed. The resistance measurement function is completed through the host computer network and serial port control, the resistance from 10 mΩ to 100 Ω can be measured, the measurement error is less than 1%, and the 32-channel resistance detection and power-on self-test functions can be completed at the same time, so that the device has the advantages of high precision, high efficiency, simple operation, good portability, high autonomous controllability and the like. The results show that the equipment can meet the requirements of high and low temperature, vibration, shock,humidity and electromagnetic compatibility, and can be widely used in field and remote measurement scenarios.更多还原
