Fluke 1623-2 On Demand

The Fluke 1623-2 earth ground tester is 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 Fluke 16232

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. With the Fluke 1623-2 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 Tester

The Fluke 1623-2 is a unique earth ground tester 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)
