图2 - 7说明分流电容对典型的高输入阻抗电压表输入端的影响。
Figure 2-7 demonstrates the effects of shunt capacitance loading on the input of a typical high impedance voltmeter.
两个电容顶部的虚线表示切换交流信号时的线圈阻抗。
The dotted line connecting the tops of the two capacitors represents the low coil impedance to ac signals.
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。
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.
