如果输入端的交流电压很大，其一部分信号被整流，于是在被测的直流信号中产生了误差。
If the AC voltage at the input is large, part of this signal is rectified, producing an error in the DC signal being measured.
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。
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.
如图2 - 2所示，输入偏置电流(IBIAS)在源电阻(RS)上产生了误差电压。
As shown in Figure 2-2, the input bias current (IBIAS) develops an error voltage across the source resistance (RS).
如果负载电阻被直接连接到伏特计的输入端子，通过继电器触点的电流会产生电压降，测得的电池电压将存在误差。
If the load resistor was connected directly across the voltmeter input terminals, the current through the relay contacts would cause a voltage drop and the measured cell voltage would be in error.
连接误差放大器另一个输入点的是一个电压分压器的中点电压。稍后我们再来讨论。
Connected to the other input of the error amp is the midpoint of a voltage divider. We'll come back to this later.
这些误差源包括热电动势、由射频干扰(RFI)经过整流而产生的偏置量以及电压表输入电路中的偏置量。
These sources include thermoelectric EMFs, offsets generated by rectification of RFI (radio frequency interference), and offsets in the voltmeter input circuit.
对电压测量来说，理想的输入电流应为零，所以，一切输入电流都代表误差。
With voltage measurements, the input current is ideally zero; thus, any input current represents an error.
同时几个皮安的输入电流会产生很大的电压偏置误差。
Also, input currents are typically many picoamps, creating large voltage offsets.
由于提取自输入电压源的电荷很大程度上仅取决于量化误差与输入噪声电压，所以电路具有高信号输入阻抗。
As the charge exerted from input voltage source is dependent on quantization error and input noise voltage to a large extent, the circuit has high signal input impedance.
从传递方程也注意到基准电压误差对较高输入电压转换器的结果影响更大。
You will also notice from the transfer function that the reference errors have more influence on the converter results with higher input voltages.
电压乘法器采用了三端输入方式和等温工作法式，以消除漏电影响和减小非平方律误差。
The input of this multiplier includes three terminals for eliminating the effect of leakage and the equal temperature operation mode for the converters is adopted to reduce the non-square law error.
当输入电压为正弦交流电压时，非晶薄带磁感应效应变化幅度的不重复性误差很小，且受温度和湿度的影响小。
The non-repeatability error and influence induced by temperature and humidity are small when the input voltage is sinusoidal.
