The main features

No test of pile

雷竞技appFluke 1625-2 KIT by simply using grounding resistance tester jaw measuring grounding resistance.When using this method of measurement, the two jaw clip on grounding rods, each jaw is connected to the tester.Completely without using grounding pile.One of the fixed voltage clamp taste should be known, another jaw measuring current.Then, the tester will automatically determine the resistance of the ground rod.This test method is only applicable to participants in the buildings or structures with the situation of the grounding system, but in most cases.If the earth is only a path, such as many residential applications, used by the no pile test method cannot provide acceptable values, you must use the potential drop test method.

Adopting pile test, without having to disconnect grounding rods - keep the combination of system on the integrity of the test.Now no need to spend time for the system and the connection of grounding rods placed on pile, it can save a lot of time.Before something you never thought about location, you can also perform ground testing, including building, cable tower, or anything you unable to gain access to the location of the land.

Fully functional tester

雷竞技appKIT is a Fluke 1625-2 different grounding tester, can complete all four types of grounding measures:

  • Three pole and quadrupole potential drop pile (to use)
  • Quadrupole soil resistivity test pile (to use)
  • Selective test (using the pile and a jaw)
  • No pile test (using only two jaw)
