The Digital Ground Resistance Tester Model 6470-B performs grounding resistance, earth coupling measurement, soil resistivity and bonding tests. This direct reading tester measures from 0.01 to 99,000Ω, 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.
