Technical Specification: 

3. Feature:

•   Transmitting unit and receiving unit are of all-in-one design, portable and lightweight.

•   Super high-power, high anti-interference performance and precision: up to 6600w (1100v×6A) power, 48Vp-p voltage range ensures to get a good result in a area with high resistance.

•   Automatically achieving compensation of self-potential, drift and electrode polarization, up to ±10V.

•   Receiving unit support transient over-voltage protection, transmitting unit supports over-voltage protection, over-current protection and AB open-circuit protection.

•   For general resistivity and IP survey function, 9 types of electrode arrays are available. Electrode distance (namely “Program”) can be inputted or called. Geometric factor K can also be generated automatically or calculated manually.

     For multi-electrode 2D resistivity imaging, up to 18 electrode arrays are available. It could scanning measure according to fixed section (including AMNB, ABMN, AMBN, AMN, MNB, A-MN-B, Sp M, Sp MN, charge M, charge MN) or continuous rolling scanning measure according to variable section (including A-M, A-MN, AB-M, AB-MN, MN-B, A-MN rectangle).

•   Program: the program can memorize 100 groups of electrode distances, avoiding repetitive input. Or you just input a program Id and step to call the corresponding electrode distances.

•  Earth resistance inspection: ground condition can be inspected at any time.

•   Mass data storage: Up to 1GB capacity (extended) enable store 5,000,000 groups measuring data (including current, voltage, SP, Ro, Ms, metal factor, TH, R, J).

•    All parameter and data are under power-failure protection; and thus data will not be lost even thought the system shuts down accidentally.

•    USB port enables it to transfer data to computer.
