Features
1.Exploration of high resolution and high efficiency resistivity measurement
The system consists of two parts: multi-function DC resisitivity meter and the multiplexor ( a) . It is used to explore matching with the high-new technology such as CT and auto convertation measure and supply of electrodes based on the theory of regular resisitivity methods.
2.Time domain DC resisitivity method and IP method
Multi-function DC resistivity meter DZD-6A can solely employ to measure and realize 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.
3.Flexible and convenient operation
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 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.
4.Convenient data translation
a. One time can store data is up to 120000 under the mode of high-density measurement.
b. One time can store total 4800 of sounding points and profiles under the mode of sole instrument of DZD-6A, of which one point includes 22 data. This data can be transmitted to a PC to digitized-translate by their corresponding software.
5.Available accessories:
The 60/ 120 channel-detector
The copper electrode with spikes
Extended temperature cables
The overburdened lines.
