Portable digital electrical exploration system ERP-1 is designed for geophysical survey performed by the following methods

• Electrical exploration by DC and AC resistivity method - vertical electric sounding (VES), electric profiling, signal generator, M3, as well as measuring of the full vector of an electric field: magnetomotive force, vector survey
• Natural electric field (self-potential, measuring of stray current field) method
• Induced polarization (IP) with INFAZ-VP version

Applications geological mapping cryopedology search and exploration of mineral deposits geoecology archeology geological engineering applied geophysics hydrogeology

Features

• The system ERP-1 provides a complex of electrical exploration methods that extends the range of solvable problems and improves the quality and accuracy of obtained results
• The system has high noise immunity (good quality of measuring unit narrow-band analoque filter is 18), that is required for urban development, sites near electricity transmission lines, railways, etc.
• Survey result, including the number of profile, survey stake, span, measurement date and time, are stored in memory
• The system ERP-1 is provided with software for data transfer from measuring unit to PC and storage of measurement results in formats compatible with software package IPI2WIN (VES and VES-IP data processing and interpretation, developed by Moscow State University)
• 'Digital' area of signal processing contains and additional method of hardware noise reduction
• Transmitter ERP-1 is supplied with two outputs, a switch tumbler for operation with different supply lines (i.e., for double-differential profiling)
• Receiver ERP-1 is supplied with two inputs, a switch tumbler for operation with different receiving lines (i.e., vertical electronic sounding with 'collars')
• The system is developed using technical decisions aimed at cost minimization
• ERP-1 is designed and developed as equipment with the state-of-art element base, available for a wide range of home consumers
