With the stakeless test method, the Fluke 1623-2 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. You can use it to perform earth ground tests in places you’ve not considered before, such as inside buildings, on power pylons, or anywhere you don’t have access to soil.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKeep your options open\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eKeep in mind, the stakeless test method works only if a bonded earth ground system exists for the building or structure under test. If there is only one path to ground, typical with many residential applications, you will need to use the fall-of-potential test method that requires stakes.\u003c\/p\u003e\n\u003cp\u003eThe 1625-2 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 1,500 records and access them easily via the USB port.\u003c\/p\u003e\n\u003cp\u003eNeed even more accuracy?
