Abstract:
In this paper we briefly introduce the site environment of Pingliang geo-electric instrument test station, the construction process of comparison device system and observation room, with which performance is tested and analyzed. The results show that the system runs stably and the output data is reliable. In the reconstruction of the observation room we make full use of the existing infrastructure, and pays attention to the design of function division, lightning protection and grounding, generic cabling and etc., which is capable of meeting the needs of geo-electric instrument comparison test. Finally, using ZD8M geo-electric resistivity meter as an example we conduct comparison and measurement analysis. The results show that the indexes of Pingliang geo-electric instrument comparison test station are in line with the relevant technical specifications.
