AEMC 6470-B Multi-Function Ground Resistance Tester
New for 2009! The AEMC 6470B replaces the AEMC 6470
|
The Digital Ground Resistance Tester Model 6470 performs grounding resistance, soil resistivity, bonding tests (2- and 4-wire Resistance) and earth coupling measurements. This direct reading tester measures from 0.01 to 99.99k Ohm, 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. The large LCD is easy-to-read and indicates grounding electrode resistance, test voltage, current and frequency. It also measures individual test electrode resistance, battery status and more depending on the measurement. The Model 6470 is Cat IV rated to 50V and is over voltage protected to greater than 250V against accidental connection to live circuits. Live voltage, if present, is also displayed on screen. In the event of a system fault, the Model 6470 can withstand 250V between any two terminals. Also included, are manual and automatic test frequency selection from 40 to 513Hz; user selectable Soil Resistivity test method (Wenner or Schlumberger); user selectable 2-Wire or 4-Wire Bond Resistance test and a Earth coupling test feature.
Additional features of the Model 6470 include: a heavy-duty field case sealed against dust and water when closed (the test button is also sealed against the elements); NiMH rechargeable batteries. An external charger powered from 120V/230V 50/60Hz is included. The Model 6470 can also be powered and charged from a 12V vehicle battery. Testing while recharging is allowed. The Ground Resistance Tester Model 6470 is rugged, easy-to-use and ideal for maintenance crews and contractors performing numerous tests. It exceeds mechanical and safety specifications for shock, vibration and drop tests called out in IEC standards.

Applications:
-
3-Point measurements of resistance to ground of ground rods and grids. 3-Point measurements are generally used when the electrode or grid can be easily disconnected.
-
4-Point tests or soil resistivity measurements. Locating areas of lowest soil resistivity is essential for achieving an economical grounding installation.
-
Touch and step potential testing measurements. These tests are recommended when the ground cannot be disconnected, where ground faults are highly likely to occur, or when the “footprint” of grounded equipment (the outline of the part of equipment in contact with the earth) is comparable to the size of the ground to be tested.
-
2- or 4-Wire tests for continuity tests on bonding or on grounding systems. This test is a DC resistive test using 250mA or more and is used to check bonding of all connection points on the ground system.
-
Earth coupling measurement and display. Used to estimate the influence of two earth resistance systems that are not connected to each other.
