AEMC 6470-B

The AEMC 6470-B Digital Ground Resistance Tester conducts grounding resistance, earth coupling, soil resistivity, and bonding tests. This reistance tester provides direct readings from 0.01 to 99,000Ω and automatically selects the optimal measurement range, test current, and frequency. Simply connect the leads, choose the test mode, press to measure, and view the results. The 6470-B can store up to 512 test results in its internal memory, which can be recalled on the display or downloaded to a PC for further analysis and reporting.
