BY2571 Earth Resistance Tester

The instrument applies to power industry, post and telecommunications, railway, communications, mining and other sectors to measure the grounding resistance of the various devices, and the conductor resistance of low resistance; this instrument can also measure soil resistivity and ground voltage. 

The instrument is a newly developed earth resistance tester, which abandons the traditional way of generating electricity by hand operation, uses advanced middle-large scale integrated circuits and applies DC/AC transformation technology to combine three-terminal measurement method and four-terminal measurement method into one model.
