AEMC Ground Resistance Tester Model 6470-B Kit-300ft

AEMC Ground Resistance Tester Model 6470-B Kit-300ft 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.   4-Point Earth Resistance Measurement Range (Auto-Ranging) 0.011Ω to 99.99kΩ Resolution 0.001 to 10Ω Accuracy ±(2% Reading +1ct) Test Voltage 16V or 32V; 41 to 513Hz Test Current Up to 250mA 3-Point Earth Resistance Measurement Range (Auto-Ranging) 0.09Ω to 99.9kΩ Resolution 0.01 to 100Ω Accuracy ±(2% Reading +1ct) Test Voltage 16V or 32V; 41 to 513Hz  Test Current Up to 250mA Soil Resistivity 4-Point Measurement Test method Wenner or Schlumberger selectable with automatic calculation Range (Auto-Ranging) 0.01Ω to 99.9kΩ; ρ max: 999kΩm Resolution 0.01 to 100Ω Accuracy (Typical) ±(2% Reading +1ct) Test Voltage 16V or 32V; 41 to 128Hz selectable DC Resistance Measurement (Bond Testing)2-Pole (with lead resistance compensation) or 4-Pole (Kelvin sensing) Range (Auto-Ranging) 2-pole: 0.12Ω to 99.9kΩ4-pole: 0.020Ω to 99.99kΩ Resolution 2 -pole: 0.01 to 100Ω4-pole: 0.001 to 10Ω Accuracy (Typical) ±(2% Reading +2ct) Test Voltage 16VDC; (+, - or auto polarity) Test Current Up to 250mA External Voltage Measurement Range 0.1 to 65VAC/DC DC, 15 to 440Hz Accuracy ±(2% Reading +1ct) General Features Memory 512 measurements (64KB) Communication USB 2.0 optically isolated, DataView software included Power Source 9.6V rechargeable battery pack with external 110/220V charger Battery Life 1500 tests typical in automatic mode Dimensions 10.7 x 9.80 x 5.12€ (272 x 248 x 130mm) Weight 7 lbs (3.2kg) with battery Case UL V0 Polypropylene Operating Temperature 32° to +113°F (0° to +45°C) Storage Temperature -40° to 158°F (-40° to +70°C) Relative Humidity Up to 90% Ingress Protection (IP) IP 53 with cover closed EMC EN 61326-1 Safety Compliance IEC 61010-1, EN 61557, 50V CAT IV, Pollution Degree 2
