电阻

Another consideration when measuring voltages from high resistance sources is the input bias current of the voltmeter.

在测量高电阻源时要考虑的另一个问题是电压表的输入偏置电流。

As shown in Figure 2-2, the input bias current develops an error voltage across the source resistance.

如图2-2所示，输入偏置电流在源电阻上产生了误差电压。

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。

The measuring appliance has the characteristic of enough big enlargement multiple and high input resistance characteristic.

仪表用放大器具备足够大的放大倍数、高输入电阻和高共模抑制比的特点。

Because of the high input resistance and low offset current, the electrometer voltmeter has minimal effect on the circuit being measured.

由于具有高输入电阻和低偏置电流，静电计电压表对被测电路的影响极小。

Given that V2 is applied to the amplifier input lead, the high input resistance of the operational amplifier is the only load on V2, and the only current drawn from the source is the very low input offset current of the operational amplifier.

若V2加到放大器的输入端，运算放大器的高输入电阻成为V2的唯一负载，而且唯一从源吸取的电流是运算放大器非常低的输入偏置电流。

Thus, input resistance loading would result in an error of 1% in this example.

这样，在这个例子中，输入电阻的负载效应将产生 1%的误差。

In order to raise measurement speed and accuracy of winding direct current resistance, step input dynamic test method is put forward in this paper.

The meter input resistance should be much higher than the source resistance.

仪表的输入电阻应当远远大于源的内阻才能满足对测量准确度的要求。

An electrometer preamplifier is used at the input to increase sensitivity and raise input resistance.

在其输入端采用一个静电计前置放大器以提高灵敏度并提高输入电阻。
