Geological Exploration Instrument DC/ IP Power Receiver to Water
Finder Underground Mineral
WDJD-4 Multi-function Digital DC Resistivity/IP Meter is our new
generation model with 32 single-chip and 24 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.
The single WDJD-4 can conduct general electrical resistivity/IP
survey with twist pair wire, iron electrodes and power source. If
WDJD-4 is used together with WDZJ-4 multiplex electrode switcher
multi-electrode cable, electrodes and power source, it can conduct
not only general electrical resistivity/IP survey but also
multi-electrode 2D Resistivity imaging.
1.Transmitting unit and receiving unit are of all-in-one design,
portable and lightweight.
2. 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.
3.Automatically achieving compensation of self-potential, drift and
electrode polarization, up to ±10V.
4.Receiving unit support transient over-voltage protection,
transmitting unit supports over-voltage protection, over-current
protection and AB open-circuit protection.
5. 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.
6.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).
7. 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.
8. Earth resistance inspection: ground condition can be inspected
at any time.
9.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).
10.All parameter and data are under power-failure protection; and
thus data will not be lost even thought the system shuts down
11.USB port enables it to transfer data to computer.
