   The AEMC Digital Ground Resistance Tester Model 6470-B is a portable measurement instrument designed to measure Ground Resistance, Soil Resistivity (two methods Wenner and Schlumberger), Bonding Resistance (DC Resistance 2-Wire and 4-Wire Kelvin sensing) and Earth Coupling resistance. This direct reading tester measures from 0.01 to 99.99kΩ and is auto-ranging, automatically seeking out the optimum measurement range and test current.

   Easy-to-use just simply connect the leads, select the test mode, press Start and read the results. Up to 512 test results can be stored in internal memory for later recall to the display or downloaded to a PC via DataView® software. The large LCD is easy-to-read and indicates ground electrode resistance, test voltage, current and frequency as well as individual electrode resistance, battery status and more.

   The Model 6470-B is Cat IV rated to 50V and is over voltage protected to more than 250VAC against accidental connection to live circuits. The voltage is also displayed on screen. In the event of a system fault, the Model 6470-B can withstand 250VAC.

   Additional features of the Model 6470-B include a heavy-duty field case sealed against dust and water when closed (the test button is also sealed against the elements); manual and automatic test frequency selection from 40 to 513Hz; user selectable 3-Pole (3-Point) Fall of Potential or 4-Pole (4-Point) Soil Resistivity test methods and user selectable 2-Wire or 4-Wire Bond Resistance test method. The Model 6470-B is powered by 9.6V, 3.5 Ah NiMH rechargeable batteries. An external recharger powered from 120/230V 50/60Hz is included and provides for testing while recharging. The Model 6470-B can also be vehicle powered from an optional 12V battery adapter.

   The Ground Resistance Tester Model 6470-B is rugged, easy-to-use and ideal for maintenance crews performing numerous tests.
