Electrostatic shielding is provided by surrounding the signal path with a conductor connected to a low impedance point in the circuit, preferably the lo input terminal of the measuring device.

利用连接到电路中一个低阻点的导体，将信号通路包裹起来，即实现了静电屏蔽，该低阻点最好是测量设备的LO输入端子。

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。
