Application:Â Â
The instrument is our new
generation model with *2 single-chip and *4 bit A/D technology on
the basis of years of experience of design and manufacture, which
could carry on Res and IP survey at the same time. It features
multiple functions, high accuracy, fast speed, high reliability and
excellent expandability. Measured data of WDJD*4 can be processed
by other multi-electrode resistivity software, which makes the
interpretation more convenient. This Instrument is widely used in metal
and non-metal mineral resources exploring, civil geophysical
exploration, railway/bridge prospecting etc, also can be used in
ground water detecting, dam foundation/flood-control dyke hidden
danger locating etc hydrological, engineering, geothermal
prospection.
Main
Features:
Transmitting unit and receiving
unit are of all-in-one design, portable and lightweight.
Â
Super high-power, high
anti-interference performance and precision: up to ***0w
(***0v×6A) power, *8Vp-p voltage range ensures to
get a good result in a area with high resistance.
Â
Automatically achieving
compensation of self-potential, drift and electrode polarization,
up to ±*0V.
Â
Receiving unit support transient
over-voltage protection, transmitting unit supports over-voltage
protection, over-current protection and AB open-circuit
protection.
Â
For general resistivity and IP
survey function, 9 types of electrode arrays are available.
Electrode distance (namely Program) can be ted or called. Geometric
factor K can also be generated automatically or calculated
manually.
    Â
For multi-electrode 2D
resistivity imaging, up to *8 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).
Â
Program: the program can memorize
**0 groups of electrode distances, avoiding repetitive . Or
you just a program Id and step to call the corresponding
electrode distances.
Â
Earth resistance inspection:
ground condition can be inspected at any time.
Â
Mass data storage: Up to 1GB
capacity (extended) enable store 5,**0,**0 groups measuring data
(including current, voltage, SP, Ro, Ms, metal factor, TH, R,
J).
Â
All parameter and data are under
power-failure protection; and thus data will not be lost even
thought the system shuts down accidentally.
Â
USB port enables it to transfer
data to computer.
