Performs grounding resistance, earth coupling measurement, soil resistivity and bonding tests.

The Digital Ground Resistance Tester Model 6470 performs grounding resistance, earth coupling measurement, soil resistivity, and bonding tests. This direct reading tester measures from 0.01 to 99,000   Ω, and is auto-ranging, automatically seeking out the optimum measurement range test current and test frequency. Easy-to-use — simply connect the leads, select the test mode, Press-to-Measure, and read the results. Up to 512 test results can be stored in internal memory for later recall to the display or download to a PC for analysis and hard copy reports.
