Refer to the instrument's instruction manual for information on a particular electrometer's internal damping feature. 关于特定静电计内部衰减电路的性能,请参阅该仪器的操作手册。
Compared to an electrometer, the voltage noise and drift are much lower, and the current noise and drift are much higher. 与测量高源内阻电压的静电计相比,纳伏表的电压噪声和电压漂移更低一些,电流噪声和电流漂移则是静电计要更低一些。
