New Generation Resistance Tester Multifunction Digital DC Instrument For Gold Mine Induced Polarization Surve

WDJD-4A New Generation Insulation Resistance Tester Induce Polarization Test Multifunction Tester

What's the WDJD-4A Multiple Function DC resistivity meter?

WDJD-4A Multi-Function Digital DC Resistivity/IP Meter , based on WDJD-3A, meets user’s most and latest needs. It features multiple functions, high accuracy, fast speed, high reliability and excellent expandability. Measured data of WDJD-4A can be processed by other multi-electrode resistivity software, which makes the interpretation more convenient. The single WDJD-4A can conduct general electrical resistivity/IP survey. If WDJD-4A is used together with WDZJ-4 multiplex electrode switcher (hereafter also referred to as WDZJ or WDZJ-4 switcher), it can conduct multi-electrode 2D Resistivity imaging.

What's can WDJD-4A measure?

(1)If you conduct general (1D) electrical resistivity survey, system configuration and layout is as shown in Fig.2-1. The system consists of one WDJD-4A mainframe, electrodes, transmitting power source.

 Positive pole (red) of the transmitting power source connects to the “DC HV +” terminal (red, positive terminal) of WDJD-4A.

 Negative pole (black) of the transmitting power source connects to the “DC HV –” (black, negative terminal) of WDJD-4A.

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

(2)If you conduct general (1D) induced polarization (IP) survey, system configuration and layout is as shown in Fig. 2-2. The system consists of one WDJD-4A 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-4A.

 Negative pole (voltage, in black) of the transmitting power source connects to the “DC HV –” (black, negative terminal) of WDJD-4A.

 Electrode A and B connect respectively to A, B connecting terminals

 Solid non-polarized electrode M and N connect respectively to M, N connecting terminal. For use and maintaining of solid non-polarized electrode, please refer to Appendix

Application of the WDJD-4A?

Application of WDJD-4A can be in metal and nonmetal mineral resources detection, city geophysical exploration, railway and bridge inspection and so on; as well as in hydrology and engineering geology such as seeking for ground water, inspect dam base and flood protection levee for incipient faults.
