我做的测试超小阻值的仪器，一般用来测试开关继电器的接触电阻！-I do ultra-small resistance test equipment, the general used to test the relay switch contact resistance!

个人设计的阵列电阻测试架，测量精度可以达到0.1 。-Individual array resistance test stand, the measurement accuracy can reach 0.1 .

计算比接触电阻。1-6 6个csv文件存放测试的IV曲线，result给出比接触电阻值以及相应的其他参数。-Calculate the specific contact resistance. 1-66 csv file to store the IV curve test result given the specific contact resistance values, and other parameters.
