If there is an ac potential difference between the shield and the measuringinstrument, there may be capacitive currents flowing through the measuring circuit that will add interference.
如果屏蔽和测量仪器之间存在一个交流电势差，则可能有电容性电流通过测量电路，增大干扰。

This instrument has the following advantages such as higher automaticity, stronger anti interference, accurate measuring, and reflecting actually the geological conditions.
该仪器自动化程度高，抗干扰能力强，测量准确，能真实地反映地质情况。
