因此，不使信号源和测量仪器之间的连接电路影响测量读数是非常重要的。

Therefore, it is important that the connection between the signal source and the measuring instrument doesn't interfere with the reading.

这个相加的电压主要为电源频率的信号，其对于电压表读数的影响决定于电压表的串模抑制能力。

This added voltage is mainly power line frequency and its effect on the voltmeter reading will depend upon the normal-mode rejection capability of the meter.
