求翻译：　　该参数表示输入电压的变化量与相应的输入电流变化量之比，电压的变化导致电流的变化。在一个输入端测量时，另一输入端接固定的共模电压。是什么意思？

This parameter indicates the input voltage variation and the corresponding variation of the ratio of input current, the voltage changes led to the current changes. In a measuring input, another input termination fixed common mode voltage.

The parameters of the input voltage that changes with the corresponding input current volume changes of volume than voltage and current changes led to the change. In an input terminal, the other input terminal when measuring the fixed the common-mode voltage.

　　Results in the use process in the instrument measuring appliance to be able to involve to the measuring range results in the question. In order to obtain the fixed voltage to result in the output, must change the operational amplifier to result in the enlargement factor. For example: When some ope

　　This parameter represents the input current of the input voltage magnitude of change and the corresponding change in the ratio of voltage change causes a current of change. An input terminal when measuring, another input common-mode voltage termination of fixed.
