Use of Syscal
This document is not a geophysics course. It is aimed at geophysicists who must carry out electrical prospecting measurements using the Syscal R1 Plus Switch 72 manufactured by Iris Instruments. Its purpose is to provide the user with some useful fundamentals and advice to achieve reliable measurements with this device and to interpret them correctly. For more details on the technique, refer to the book Water, Sanitation and Hygiene for Populations at Risk (2006) published by Action Against Hunger on the Online Geophysics Course (http: //www-ig.unil. ch / cours / index.htm) of the University of Lausanne (from which this document draws heavily), and to the technical documents published by Iris Instruments on their website (http://www.iris-instruments.com/index .html). The document is organised into three sections:
- The first section presents the definitions of the main terms used, the notions of electrical resistivity and the measurement techniques used.
- The second section focuses on the Syscal R1 Plus device, its mode of operation and its use.
- The third section presents some examples of the results of electrical surveys carried out using this device.
Other examples can be found in ACF mission reports or on the web. However, it is important to bear in mind that this document is not intended to replace the Syscal User Manual, which remains the reference document for this device. In the Appendix, some interesting technical documents edited by Iris Instrument are presented.
