Measurer and recorder of electrical signals for electrical geophysical surveys

Abstract

Abstract To conduct research by electrical prospecting, instruments for measuring and recording electric fields with unique characteristics are necessary. Such recorders should work with signals that vary over a very wide dynamic range, as well as over a wide frequency range. The acquisition of ready-made functionally complete recorders for these purposes is impossible due to the lack of such devices. These devices must work effectively both in standalone mode and in telemetry mode. High accuracy of data binding to absolute time is very important. A set of requirements for these devices requires the development and manufacture of recorders.
