The AEMC 6472 Multi-Function Ground Resistance Meter measures ground resistance (with and without clamps), bond resistance, earth coupling, touch and step potential, and soil resistivity. Measures from 0.01k? to 99.99k? with an auto-ranging feature to seek out the ideal measurement range test frequency and test current. Includes DataView software designed to analyze and display recorded measurements.
