The Fluke 1623 earth ground tester can perform all four types of earth ground measurement. Specifically, the tester is able to measure earth ground loop resistances using only clamps â€“ called Stakeless testing. This method doesnâ€™t require the use of earth ground stakes or the disconnection of ground rods.
One-button measurement concept
â€¢ 3 and 4-pole earth ground measurement
â€¢ 4-pole soil resistivity testing
â€¢ Selective testing, no disconnection of ground conductor (1 clamp)
â€¢ Stake less testing, quick ground loop testing (2 clamps)
