AEMC 6472 Ground Resistance Tester

The AEMC 6472 performs 2- and 4-point ground resistance testing, 3-point fall-of-potential, soil resistivity, selective ground testing, and bond resistance measurements. It offers test frequencies from 41 Hz to 5078 Hz, voltages of 16V or 32V, and up to 250mA test current. This unit offers auto frequency selection and can store up to 512 test results.

The AEMC 6472 + 6474 GroundFlex Kit, in stock at Advanced Test Equipment Rentals, is a specialized configuration that can perform ground testing on live transmission towers without disconnecting the overhead ground conductor.
