对于直流电流测量﹐在电流通道串联一电流分流器﹐将电流转换成直流电压信号。
For DC current measurement, a current shunt is place in series in the current path and convert the current to a DC voltage signal.
跨接在电压源上的任何外部分流电阻都会使测量的电压衰减，如图2 - 3所示。
Any external shunt resistance across the voltage source will attenuate the measured voltage, as shown in Figure 2-3.
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.
