Only one high-quality resistor in the signal path and using the Swiss made precision attenuator with gold contacts for low contact resistance and longtime durability.
一高质量电阻器在信号道路和使用瑞士与黄金接触适合低接触电阻和长期的耐久性一起使精密衰减器内只。
If using a separate current source and voltmeter to make low resistance measurements, each instrument must be checked for non-ohmic contacts.
如果使用分离的电流源和电压表来进行低电阻测量，则必须检查每台仪器的非欧姆接触情况。
Can start the flow of contacts and dynamic friction resistance is to minimize the friction resistance, it can save energy, easy to get a higher velocity.
由于流动接触可使起动磨擦阻力及动磨擦阻力为极小，因此可以节省能源，容易得到较高运动速度。
