Its main specifications include Contact Resistance, Insulation Resistance, -Voltage strength, Phase Characteristics, and so on. These specifications are usually measured with traditional method, that needs Oscilloscope, Ohm Table, and other apparatus.
它的主要技术指标有：接触电阻、绝缘电阻、抗电强度、相位特征等等，对这些参数的测试目前一般采用传统的测试方法，用传统的仪器如示波器、兆欧表等，测试时需要每个通道依次接线读数，既费时又费工。
