What instruments are used in building lightning protection testing?
Ground resistance tester is to abandon the traditional artificial hand power generation mode, using advanced large scale integrated circuit, application of DC/AC technology will transform three terminal and four terminal measurements with a model of the new digital ground resistance tester.
Test with a ground resistance tester.
The utility model is suitable for measuring the grounding resistance of various devices and measuring the resistance value of a low resistance conductor, such as power, post and telecommunications, railways, communications, mines, etc., and also can measure soil resistivity and earth voltage. Ground resistance tester should be kept indoors to maintain its ambient temperature 0 to 40 DEG C, relative humidity of not more than 80 percent, and in the air can not contain enough to cause corrosion of harmful substances.
