Product introduction
Excellent grounding system is very improtant to ensure the power, telecommunications, electrical equipment safe and reliable operation. Grounding resistance grounding system size is based on the quality of the merits of the judgment. Accurate, fast, simple and reliable grounding resistance measurement method, the area has become a lightning protection and grounding technological advances are urgently needed. NASJX double clamp earth resistance tester for telecommunications, electricity, weather, room, power distribution lines, tower transmission lines, gas stations, factories grounding, lightning and so on.
NASJX has traditional fight auxiliary earth ground resistance measurement functions, also has no auxiliary measuring the unique features of the earth, changing the traditional testing ground resistance measurement principle and means: Double clamp mouth non-contact measurement technology eliminates the need to fight auxiliary earth, and without the grounding body and load isolation, to achieve an online survey. In the single-point grounding system, strong interference and other conditions, can be used to fight the auxiliary earth electrode measurement measurement.

Product information
1, jaw and host as a whole set. To avoid measurement errors, do not use the jaw of NASJX Double Clamp Ground Resistance Tester hosts for other host.
2, must keep iron core contact surfaces of the jaw clean, or else contaminated instrument jaw will reduce measurement accuracy.
3, keep the jaws closed well during the test to avoid stuck phenomenon.
