Archaeology Exploration DC Geophysical Resistivity Meter With Electrodes


General (1D) electrical resistivity survey, consists of one WDJD-3 mainframe, electrodes, transmitting power source.

General (1D) induced polarization (IP) survey. The system consists of one WDJD-3 mainframe, electrodes, solid non-polarized electrodes, transmitting power source.

Positive pole (red) of the transmitting power source connects to the “DC HV +” terminal (red, positive terminal) of WDJD-3.

Negative pole (black) of the transmitting power source connects to the “DC HV –” (black, negative terminal) of WDJD-3.

Electrode A and B connect respectively to A, B terminals, and potential electrodes M and N respectively to M, N connecting terminals.

Regarding operation of this system, please refer to Section Two and Section Three.
