其次，低阻值电阻器降低了输入时间常数，使仪器的响应时间更短。
Second, lower resistor values reduce the input time constant and result in faster instrument response time.
镀c材料的微动接触电阻值远高于镀金材料的电阻值，低接触压力下镀c材料的微动接触电阻不稳定。
Contact resistance of carbon-plated material is much higher than that of gold plated materials. Low contact force will result in unstable resistance of C-plated material.
