Description
The E*0DN Three Dimensional High Density Multi-Electrode
Resistivity Survey System is a new type of electrical
methodology device. It uses software-controlled data acquisition
and electrode control routines and the data is presented
graphically in real-time for ease of real-time monitoring of data
quality.
Functions
This device can operate all kinds of equipment for high-density
resistivity tests, and has self custom data acquisition monitoring
capabilities. Because the device has a built-in high performance
computer, when matched with suitable data processing software, is
fully capable of doing on-site data processing.
Main Properties:
1. Using a distributed design and *-pin calbes, the system is
capable of connecting ****5 electrodes to meet the needs of
profiling and 3D high density surveying.
2. Besides standard high density equipment, it also has an open
electrode editing system, allowing the user to arbitrarily define
the input voltages and other parameters of the powered electrodes
AB and measurement electrodes MN as needed.
3. It has a binning filter to effectively suppress ground
electrical interference, raising the signal to noise ratio.
4. Ground resistance testing and electrode self-test capability
gives maximum assurance on the quality of the test materials. It
has real-time display of the resistivity diagram, current positions
of the powered and measurement electrodes, supply current, and
potential curve.
5. Data acquisition can be stopped at any point to undergo
electrode shielding, outlier filtering, or applying new
settings.
Electrode Switch Main Properties
1. Self-addressing; code runs after connecting with E*0DN.
2. Built-in microprocessor handles commands from the main computer
to control workflow.
3. Up to *0 m between nodes satisfies most surveying needs.
4. Small, light, and sturdy design, well-suited for field work.
5. Power supply cables and measurement cables have different
diameters and shielding to meet the needs of using high current
while minimizing inter-cable interference.
