dc high impedance voltmeter 高阻抗直流电压表
Figure 2-7 demonstrates the effects of shunt capacitance loading on the input of a typical high impedance voltmeter.
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。
It must also be remembered that any voltmeter is a high-impedance device and that an ideal voltmeter draws no current from the circuit being tested.
我们需要记住的是任何伏特计都是一台高阻抗设备并且一个理想的伏特计是不从被测试的电路分出电流的。
