Fluke EI-1625 Selective/Stakeless Clamp Set (1625)

The Fluke EI-1625 Selective/Stakeless clamp set (1625) is used in conjunction with the Fluke model 1625 to perform both selective and stakeless testing.  Selective testing involves using one clamp, along with an Earth ground stakes for the purpose of Earth ground loop resistant values for one Earth ground electrode.  The method of stakesless testing uses both of the clamps that are provided as part of the package to perform Earth ground loop resistance measurements without the use of stakes. 

Both of these methods of testing have a strong advantage of providing you with measurements with no disconnection from the grounding system, making this a safe and quicker way to get the job done.  This package is included when you purchase the Fluke 1625 Kit.  Both of the clamps have a 2-inch inner diameter (50.8 millimeter).
