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.

Fluke Earth Ground Tester offers fast, accurate earth ground testing using all four test methods. The Fluke 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 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. Keep your options open If a bonded earth ground system does not exist for the building or structure under test, and there is only one path to ground, you can use the to perform the fall-of-potential test method with stakes.
The offers other advanced features including: Automatic Frequency Control to identify existing interference and choose a measurement frequency to minimize its effect, thus providing a more accurate earth ground value.
The is also very easy to use. World class accessories speed set up and test time. And the tester tells you which stakes or clamps to connect for each test. The large rotary switch and buttons are easy to operate even with a gloved hand.
And you can store up to records and access them easily via the USB port.
