General Electrometer Considerations: a discussion of techniques and error sources that affect high impedance measurements in general.

一般静电计要考虑的问题：一般性地讨论影响高阻测量的技术和误差来源。

When measuring the charge on a device such as a capacitor, it's important to disable the zero check of the electrometer first, and then connect the capacitor to the high impedance input terminal.

在测量一个器件，如电容器上的电荷时，重要之点是要首先关闭静电计的零点检查功能，然后再将电容器连到高阻抗输入端。

However, when the hi terminal of the electrometer is connected to the low impedance power supply, this AC current (I) flows through the electrometer (im), as illustrated in Figure 2-41.

然而，如果静电计的HI端连到电源的低阻端，则该交流电流(i)就流过静电计(IM)，如图2 - 41所示。
