A low-cost/hand-made equipment for resistivity profiling using passive devices and general measurement tools.


Abstract
Evolution of technology of electronics gives geophysical equipment huge benefit. A resistivity equipment composed by new passive devices and general measurement instruments is demonstrated. Constant current diodes are used for current control. A general 24bit A/D converter is tested for noise and drift evaluation. Data obtained by the composed equipment is similar as a conventional equipment.
