电流的

With voltage measurements, the input current is ideally zero; thus, any input current represents an error.

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。

Input offset current can be determined by capping the input connector and selecting the lowest current range.

输入偏置电流可以通过盖上输入连接器并选择最低的电流量程来决定。

Currents can be internally generated, as in the case of instrument input offset current, or they can come from external sources such as insulators and cables.

这种电流可以在内部产生，如仪器的输入偏置电流；也可以从外部而来，如来自绝缘子和电缆。

Note that the input offset current can be partially nulled by enabling the INSTRUMENT current suppress with the input terminals disconnected and ZERO CHECK open.

要注意，在仪器电流抑制的条件下，即输入端不连接和"ZERO CHECK"开路时，输入失调电流可部分无效。

The instantaneous current when the transistor is turned on is very high and some small-signal transistors will not deliver the required current.
