Fluke 1623-2: GEO Earth Ground Resistance Meter

Fluke 1623-2 Earth Ground Tester performs all four ground tests quickly and accurately.

The Fluke 1623-2 earth ground tester measures earth ground loop resistances using only clamps, only stakes, or one clamp and stakes. With the stakeless test method, the Fluke 1623-2 is able to measure earth ground loop resistances for multi-grounded systems using only current clamps. This technique eliminates the dangerous, and time consuming job of disconnecting parallel grounds, and finding suitable locations for auxiliary ground stakes. You can use it to perform earth ground tests in places you’ve not considered before, such as inside buildings, on power pylons, or anywhere you don’t have access to soil.

The new Fluke 1623-2 and 1625-2 GEO Earth Ground Testers offer data storage and download capabilities via USB port. World class accessories will simplify and speed up testing time.

Product features:
• 3- and 4-pole Fall of Potential, earth resistance loop testing
• 4-pole Soil Resistivity testing
• Selective earth ground rod testing using 1 clamp
• Stakeless earth ground rod testing using 2 clamps
• IP56 rated for outdoor use
• Professional carrying case
• USB data storage and transfer

Stakeless testing
The Fluke 1623-2 and 1625-2 earth ground testers 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.
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.

The most complete testers
The Fluke 1623-2 and 1625-2 are distinctive earth ground testers that can perform all four types of earth ground measurement:
• 3- and 4-Pole Fall of Potential (using stakes)
• 4-Pole Soil Resistivity testing (using stakes)
• Selective testing (using 1 clamp and stakes)
• Stakeless testing (using 2 clamps only)
The testers are also 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 complete model kit comes with the 1623-2 or 1625-2 tester, test leads, 4 earth ground stakes, 3 cable reels with wire, 2 clamps, batteries, and manual— all inside a professional Fluke carrying case.
