The Fluke 1625-2 offers simpler, faster earth ground tests than ever before. With internal memory storage of up to 1500 records, accessible via USB port for rapid data transfer and viewing of results. The earth ground tester also gives you world class accessories that take the tedium out of earth ground testing. New wire reels speed up setup and tear down time as much as 50%. Heavy duty stakes can be hammered into dry, hard soil. And new colour-coded wires make setup simple and help eliminate mistakes.
The Fluke 1625-2 is a unique earth ground tester that can perform all four types of earth ground measurement:
Easy to use, for each test the testers inform you which stakes or clamps need to be connected and the large rotary switch can be used even with a gloved hand.
The Fluke 1625-2 is different from its sibling product the 1623-2 in a number of ways. The 1625-2 offers automatic frequency control (AFC) which helps identify existing interference and chooses a measurement frequency to minimize it's effect.
R* Measurement calculates earth ground impedance at 55Hz to more accurately reflect the earth ground resistance that a fault-to-earth ground would see. While also offering adjustable limits for quicker testing.
The 1625-2 is 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 are connected to the tester. No earth ground stakes are used at all. A known, fixed voltage is induced by the clamp and the current is measured using the second clamp. The 1625-2 then automatically determines the resistance of the earth ground rod.
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.
