Fluke 1625-2 GEO Earth Ground Tester

Description

The Fluke 1625-2 Earth Ground Tester are able to measure earth ground loop resistances using only clamps. With
this test method, two clamps are placed around the earth ground rod and each are connected to the tester. No
earth ground stakes are used at all. A known, fixed voltage is induced by one clamp and the current is measured
using the second clamp. Then the tester automatically determines the resistance of the earth ground rod. The 1625-2
features automatic frequency control and adjustable limits for quicker testing. This test method only works if a bonded earth ground system exists for the building or structure under test,
but most are. If there is only one path to ground, like at many residential applications, the Stakeless method
will not provide an acceptable value and the Fall of Potential test method must be used. With Stakeless testing, the earth ground rod does not need to be disconnected—leaving the bonded earth ground
system intact during test. Gone are the days of spending time placing and connecting stakes for each earth ground
rod on your system a major time saver. You can also perform earth ground tests in places you’ve not considered
before: inside buildings, power pylons, or anywhere you don’t have access to soil.
