Features    
Exploration of high resolution and high efficiency resistivity measurement  
The system consists of two parts, one is multi-function DC resisitivitymeter and the other is multiplexor (��. It uses to explore matching with the high-new techniques such as CT and automation of electrodes converting to measure and supply, based on the theory of regular resisitivity methods.   
Time domain DC resisitivity method and IP method  
Multi-function DC resistivitymeter DZD-6A can solely employ to measurement and that it realizes resisitivity method and IP method under the conventional mode. And this method possesses plenty of measuring parameters: Spontaneous Potential Vsp, primary field potential Vp, supply current I, apparent resisitivity RO(ps), apparent polarizablility M1-6, half-life time Th, degree of damping D, synthetic excited electron parameter Zp and degree of deviation R.
Flexible and convenient operations  
This instrument can auto-compensate the cases of self-potential, drifting and polarized electrodes by employing a full digital auto-measurement. And the result displays on a large LCD screen which can list a total 14 kinds of method models under the High-Density measurement. At the meantime, the sole DZD-6A measurement has 9 kinds of electrode arrangements and real-time display the measured curves.   
Convenient data translation  
a. One time can store data is up to 120000 under the model of high-density measurement.  
b. One time can store total 4800 of sounding points and profiles under the model of sole instrument of DZD-6A, of which one point includes 22 data. This data can be transmit to a PC to digitized-translate them by their corresponding software.
