| Abstract: | The reliability of the cable is the precondition of the reliability of the auto test system.Two methods to test the resistance of the cable is introduced and a testing instrument based on this method is designed. The method and implement of the software and hardware are discussed in detail;The experimental results prove that the testing instrument realizes the automatic test of cables and improve the measurement precision. |
