Resumen:
A programmable automated resistivity device was designed and constructed using an open-source electronic platform. In this work we present a low power version of the device that was implemented for physical model laboratory studies.The low power version of the device for physical model measurements use a 24V battery system to generate the A-B current flow. A resistance of 560Ω limits the current flow to less than 40mA. We present results obtained in a simple physical model to verify the performance of the automated resistivity device developed. We program the electrodes positions to make in line dipole-dipole, Schlumberger-Wenner, and ϒ11n configuration surveys. The tomography obtained from the D-D and S-W data show an excellent agreement with the physical model, the convergence is of 1% for these configurations. ϒ11n configuration give a convergence of 12%.
