Earth Voltage and Resistance. 3. The Terra EZ Res Pro (unit) is warranted against defects in materials and workmanship for one year from date of purchase. Terra Exploration Group (TexGru) may, at its’... - Page 3 Terra EZ Res Pro---Easy Resistivity Guide Thank you for purchasing the Terra EZ Res Pro, the easiest-to-use, yet, very sophisticated earth resistivity (and resistance) scanner. The complete package includes the electronic host unit within a special protective waterproof case. Contained within a...
- Page 4 A. General Provisions of This Guide: This guide will provide instruction in the general use and understanding of earth resistivity. It will concentrate on and show how to conduct two-probe resistivity arrays. Under the four probe category, it will give a basic understanding of Wenner, Schlumberger and Dipole-Dipole Resistivity arrays.
- Page 5 To calculate the apparent resistivity, the EZ Res Pro measures the voltage drop from the current sent from the C+ and C- wires to the current received by the P+ and P- wires. The strongest reading position is in the center of the probes.
- Page 6 Terra EZ Res Pro. The second probe will be connected via alligator clip to the black long wire, which will be connected to the black and green jumper wire set, which then plugs into to the black and green binding posts on the face of the Terra EZ Res Pro.
- Page 7 C. How-to examples: use of the two-probe array is shown as it is the simplest array and the fastest/easiest scan to conduct: 1. How to find caves/tunnels: The illustration below shows overhead and cross-section views of a two-probe resistivity array in a hypothetical search for a cave or tunnel. First, Control Scans are conducted to determine “NORMAL”...

2. How to find water: The illustration below shows overhead and cross-section views of a two- probe resistivity array in a hypothetical search for water. The methodology is exactly the same as explained in the cave/tunnel example with the only difference being that an indication of water at some depth will exhibit a significant decrease in resistivity numbers as water is generally more electrically conductive than the surrounding soil. -

3. How to find metallic mineral veins or large metal caches: The illustration below shows overhead and cross-section views of a two-probe resistivity array in a hypothetical search for a metallic mineral vein. The methodology is exactly the same as explained in the water example whereby resistivity at some depth will exhibit a very significant decrease in resistivity numbers as metallic mineral veins are always more electrically conductive than the surrounding normal soil. - Page 10 (maintain original center point) each time by a factor of 1.585X previous spread and a new scan is conducted. The EZ Res Pro stores the results of each scan internally, but it is a good idea to manually record the probe spacing and apparent resistivity results of each scan for easy and quick reference.
