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 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 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.

Technical Data

The new 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.
• 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
• Rugged carrying case

In addition, the Fluke 1625 offers these advanced features
• Automatic Frequency Control

AFC - identifies existing interference and chooses a measurement frequency to minimize its effect, providing more accurate earth ground value
• R* measurement - calculates earth ground impedance at 55 Hz to more accurately reflect the earth ground resistance that a fault-toearth ground would see
• Adjustable limits - for quicker testing

Stakeless testing

The Fluke 1623 and 1625 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 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 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 and 1625 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.
