    Model 6470 can also measure the resistance of the auxiliary rods. The nominal test frequency is 128Hz (Square Wave) which is typical for ground testers. In certain cases measurements, at nominal test frequency may be affected by stray signals in the ground. The Model 6470 automatically scans the stray volt- age noise and internally selects the best test frequency between 41Hz, 55Hz, 92Hz, 110Hz, 119Hz, 128Hz, 476Hz for the optimum measurement. For advanced users, the test frequency can be manually selected between 41Hz and 513Hz. Details on ground resistance measurements and rod distances are available in the AEMC Understanding Ground Resistance Testing Workbook CD that was ® included with the instrument. Please note that the AEMC ground kits include color-coded leads which match the ® terminals to facilitate connections and to ensure that adequate test lead lengths are provided.

    NOTE: That the two center auxiliary rods are the current electrodes, and their spacing corresponds to the depth of the resistivity measured. A four-electrode piece of equipment, which can be made available in the physics laboratory, was designed and fabricated for measuring current and potential val- ues so as to obtain the resistivity values. Readings taken from our chosen location using both Wenner and Schlumberger arrays were analyzed. In the resistivity method, the Wenner configuration discriminates between resistivi- ties of different geoelectric lateral layers, while the Schlumberger configuration is used for the ‘depth sounding’. The theory behind the resistivity method was intro- duced with some degree of sophistication. Experimentally determined values of depth to surface were correlated with the values determined from the excavated site and this gave a good correlation. It was observed that the resistivity value in the chosen location increases with the depth and the Schlumberger method was seen to have a greater penetration than the Wenner.

  • Page 50 NOTE: The distances “A” and “d” cannot be modified during the measurement. During the measurement, you can use the Hz/OPTIONS and buttons to modify ► the measurement frequency, between 41 and 128 Hz only. If the measurement is unstable and results are inconsistent, trigger the measure- ment again to check that the problem is not a faulty connection. Any change to the “A” or “d” distance parameters after the measurement will auto- matically result in a new resistivity calculation by the instrument. Several measurements can be saved for different distances in a single OBJ:TEST test location. In this way, the resistivity can be determined as a function of the dis- tance, and therefore of the depth of the measurement location. Ground Resistance Tester Model 6470...
