Data Acquisition and Control Software for Automated Resistivity Measurements

Toll, D.G.; Hassan, A.A.

Abstract

Automated multi-electrode resistivity systems now allow rapid and efficient data acquisition of electrical resistivity measurements to address a wide range of hydrogeological, geotechnical and environmental problems. In this work, a flexible data acquisition and control software package has been developed to acquire resistivity data using configurable electrode arrangements. The user friendly and reliable acquisition software has been used to integrate the hardware and to control the resistivity data collection process. The user can remotely set the current and voltage; multiplex 64 electrodes interchangeably as current and voltage electrodes in a fully automated procedure to collect real-time resistivity data. The package developed has been tested using a wide range of high precision reference resistors and compacted clay soils, and the results have been correlated with those acquired with commercial standard instruments. The results demonstrate high precision, accuracy, and resolution of the collected data with a maximum error of 0.8%.
