  4. Introduction. The Fluke 1621 Earth Ground Tester (referred throughout as the “Tester”) is an easy to use instrument for measuring the resistance to earth ground of a specified earth ground electrode. The Tester can perform a 3-pole fall-of-potential test conforming to IEC/EN 61557-5.

  5. L. L = 1m. Figure 1. Soil Resistivity. Soil resistivity primarily depends on soil type (like farming soil, dry sand, moist sand, concrete, gravel), although seasonal changes can also influence resistivity. Dry soil has a higher resistivity than moist soil, and frozen ground has a higher resistivity than dry, warm sand.

  6. The Fluke 1621 is an easy-to-use earth ground tester. The first line of defense in detecting reliable ground connections, the unit features basic ground testing methods including 3-pole Fall-of-Potential as well as 2-pole ground resistance. Its convenient size, rugged holster, and large, clear LCD display make it an ideal

  7. The Fluke 1621 Earth Ground Tester is a rugged, easy-to-use tester for three-pole ground resistance measurements and two-pole ac resistance measurements. Earth ground resistance is measured by installing earth ground test electrodes, and testing with the Fluke 1621.
