Any external shunt resistance across the voltage source will attenuate the measured voltage, as shown in Figure 2-3.
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。
Although input bias current is a common source of this type of error, currents generated by external circuits can also result in errors due to voltage drops across the source resistance.
虽然输入偏置电流是这种误差的常见来源，但是外电路产生的电流在源电阻上形成的电压降也能引起误差。
However, the utility source for a plant may contain additional harmonic voltage distortion arising from external sources.
然而，对工厂实用电源可能包括由外部电源引起的额外的谐波电压畸变量。
