Fluke 1623-2 KIT Earth Ground Tester

The Fluke 1623-2 KIT Earth Ground Tester measures ground loop resistance using only clamps. With this measurement method, two clamps are clamped onto the ground rod, and each clamp is connected to the tester. No ground stakes are required at all. One clamp induces a known, fixed voltage, while the other clamp measures the current. The tester then automatically determines the resistance of the ground rod. This test method is only applicable where a grounding system exists in the building or structure under test – which is the case in most situations. If there is only a single path to ground, such as in many residential applications, the stakeless method cannot provide an acceptable value; the fall-of-potential test method must be used.

With stakeless testing, there is no need to disconnect the ground rod – the integrity of the bonded grounding system is maintained during testing. You no longer need to spend time placing stakes and connecting ground rods to the system, saving a significant amount of time. You can also perform ground testing in locations you might never have considered before, including inside buildings, on transmission towers, or anywhere you do not have access to soil.

A Versatile Tester

The Fluke 1623-2 KIT is a ground tester like no other, performing all four types of ground measurements:

• 3- and 4-Pole Fall-of-Potential (using stakes)

• 4-Pole Soil Resistivity (using stakes)

• Selective Testing (using stakes and 1 clamp)

• Stakeless Testing (using only 2 clamps)
