In order to implement the automatic test function on the cable in weapon equipment, combined with the characteristic used in the past, a sort of minitype, convenient carried, applied cable test apparatus has been developed. The overall design scheme and realization method of the software are presented, and technology of embed is used in the hardware, the miniature cable test apparatus is designed. The result indicate, the tester is capable of processing auto measurement on the electric performance, such as turn-on resistance and insulation resistance, it is able to quickly check the possible faults on the cable, reduce the measuring time, and improve the test efficiency.% 为实现某武器装备电缆的自动检测功能，结合用户的使用特点，研制出了一台小型、便携、实用型的电缆测试仪。本文主要阐述了该系统的总体设计方案和软件设计方法，在硬件方面结合嵌入式技术，设计出了小型化的电缆测试仪。试用结果表明，该测试仪能对电缆的导通电阻、绝缘电阻等电气性能参数进行自动测量，及时快速地显示电缆存在的故障，可以缩短检测时间，提高检测效率。
