The Fluke 1623 and 1625 GEO earth ground testers offer an innovative solution, called stakeless testing, to make your earth ground loop resistance testing quicker and easier. No need for a separate earth ground clamp.
The Fluke 1623 and 1625 GEO earth ground testers are easy to use. For each test, the Fluke 1623 and 1625 GEO earth ground testers inform you which stakes or clamps need to be connected and the large rotary switch can be used even with a gloved hand.
In addition the Fluke 1625 GEO earth ground tester offers these advanced features:
The Fluke 1623 and 1625 GEO earth ground testers are able to measure earth ground loop resistance using only clamps. With this test method, two clamps are placed around the earth ground rod and each is 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.
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. Earth ground tests can also be performed in places you've not considered before: inside buildings, power pylons, or anywhere you don't have access to soil.
The complete model kit comes with the Fluke 1623 or 1625 GEO earth ground tester, test leads, 4 earth ground stakes, 3 cable reels with wire, 2 clamps, batteries and manual - all inside a rugged Fluke carrying case.
