Overview
The WDJD-4A multifunctional digital DC induced polarizer is used as the measurement and control host. It integrates the transmitting and receiving functions and has many excellent performances, such as high-precision voltage and current measurement, wide range, strong anti-interference ability, etc.
Can be used with WZDJ-4 or WZDJ-120 multi-channel electrode converter to achieve switching control of multiple electrodes to meet different measurement requirements and electrode arrangements.
Depending on the measurement method, centralized high-density cables or distributed high-density cables and corresponding electrodes can be used to achieve the transmission and measurement of electrical signals.

Electrode layout and measurement method
The electrode layout is completed in one go. Dozens to hundreds of electrodes can be arranged at each measuring point of the observation profile at the same time. Then, different electrode combinations can be automatically switched for measurement through the programmable electrode conversion device, which can effectively reduce the interference and measurement errors caused by electrode settings.
Data acquisition and processing
data acquisition is automated or semi-automated, with fast acquisition speed, about 2-5 seconds for each measuring point, which can quickly obtain a large amount of data, and can process data in real time on site and offline. Through professional software, multiple measurement parameters are analyzed and inverted to obtain two-dimensional or three-dimensional geoelectric cross-section diagrams, which intuitively reflect the underground geological structure.
Measurement accuracy and resolution
It adopts high-density point measurement and small electrode spacing, which can provide richer geoelectric information, has high lateral and vertical resolution of geological bodies, can detect smaller-scale geological anomalies, and the measurement accuracy is generally around ±1% to ±2%. The small signal measurement accuracy is also high, which can meet the needs of fine exploration such as engineering geology and hydrogeology.
Scope of application and application effects
It is suitable for engineering geological survey, hydrogeological survey, environmental geological research, mineral resource exploration and other fields. It is effective in detecting shallow geological structures, underground cavities, goafs, fault fracture zones, etc. It can quickly obtain underground geological information and provide scientific basis for engineering design, construction and geological disaster prevention.
