1D Vertical Electrical Sounding Investigation Geophysical Electrical Resistivity Meter

WDJD-3A Multi-function Digital DC Resistivity/IP Meter can conduct 1D electrical resistivity survey, in association with only power source, electrodes and ordinary cables. In this case, what electrode array applicable is the first 8 electrode arrays introduced in Section One Electrode Arrays of General Electrical Resistivity Survey, namely, four-pole vertical electric sounding(4P-VES), Combined electric sounding(3P-VES), four-pole electrical profiling (4P-PRFL), Combined electrical profiling (3P-PRFL), Rectangle/Middle Gradient (RECT), dipole-dipole (DIPOLE), IP survey in Well-Well Azimuth Sounding(IP-BUR), Five-pole Longitudinal Axis Electical Sounding (5P-VES).Except for access to these electrode arrays, user can also input geometric factor K value directly through Item 9 Input K value for some special electrode array configurations that is not available in system.

Application
