  • Resistivity system voltage output

    One limit of FlashRES resistivity meter is its voltage output. It can output maximum voltage of 350v, this is because the multi-core cable of the FlashRES cannot withstand voltage over 350v. the multi-core cable contains 32 small wires, voltage higher than 350v will damage these wires and make the cable short circuit. We thus limit the maximum voltage output for safety reasons. Reference ...

  • Cave Detection: Testing the Industry’s First Electrical Resistivity Imaging Instrument - Case Study

    AGI first tested the Sting—the predecessor to the SuperSting instrument—in October 1994. This data set began the electrical resistivity imaging industry. Background In 1993, the Sting instrument was created—but ...

  • Roll along resistivity survey

    A roll-along survey is a method for operator to survey a long line. After the initial survey, the operator will leave one cable on the ground and move the instrument and cables forward. So there is always one cable overlap between two surveys. Alternatively, the operator can divide the cable in half and only overlap 16 electrode spacing. In this way, the opearator could complete the survey ...

  • The key advantages of FlashRES resistivity meter

    FlashRES-UNIVERSAL is the first instrument in the world that can fully utilise all its electrodes during data collection.  It is a significant technological breakthrough. FlashRES-UNIVERSAL has following key advantages: FlashRES is a 61-channal resistivity/IP system and it is extremely fast For each current injection, conventional resistivity systems usually collect ...

  • Compare popular resistivity meters with FlashRES

    Although most resistivity meters nowadays can collect resistivity, IP and SP data and most of these systems are multi-channal resistivity meters, there is still a technical gap between traditional and next generation resistivity meters. FlashRES has six to 8 times more channel than traditional system, this means larger data quantity, which could help the resistivity inversion image ...

  • The suitable battery for FlashRES resistivity meter

    Air freight battery pack is extremely diffculty in Australia, this makes installing internal battery to FlashRES resistivity meter counter-productive for ZZ. We thus use an external battery and connect it with our system. The correct external battery for our system should be a 12 volt truck/car battery of ≥ 90 Amp/hr is needed. Reference ...

  • What is 61-channel resistivity meter?

    FlashRES resistivity meter has 64 electrodes, it uses one common ground electrode, two electrodes as current injection electrodes. For each current injection between A and B, the FlashRES resistivity meter measures the potential on remaining electrodes against the common ground electrode. In this way, 61 MN voltages are measured and hence FlashRES is a 61 channal resistivity meter. ...

  • Surface resistivity survey case study 1

    The purpose of this surface electrical resistivity survey was to delineate the event direction of a gold ore deposit. The surface electrical resistivity survey uses a 10m interval cable, that permits the FlashRES 61 channel resistivity meter to detect depth up to 120m. The depth is dependent on the cable length.  The system found an occasional resistive band from 0-350m. This knowledge was ...

  • Exploring Soil Resistivity in Lima, Peru - Case Study

    In April 2013, in partnership with SensorVital and Pontificia Universidad Católica del Perú, AGI conducted a workshop focused on exploring the resistivity of shallow soil at Pontificia Universidad ...
