AEMC 6472

The AEMC 6472 Ground Resistance Tester is a portable instrument that measures bond resistance, ground resistance (with or without clamps), soil resistivity, earth coupling, and step & touch potential. When paired with the GroundFlex™ Adapter Model 6474, it can also test power transmission tower and tower leg ground resistance. This auto-ranging tester measures from 0.01 kΩ to 99.99 kΩ, with adjustable test frequencies from 40 Hz to 5078 Hz, ensuring accurate results even in challenging conditions with high stray currents. This ground resistance tester stores up to 512 test results, which can be recalled on the display or downloaded to a PC using the included DataView® software.
