Caution
1. The instrument early in the design has been fully taken into account the use of the extreme
environments . But still have to pay attention to the correct method of operation, please do not fall
equipment deliberately, proper use will extend the life of the instrument .
2. The instrument is not waterproof, please do not immerse the instrument in water or operate in
the rain.
3. Please do not strike LCD screen, do not expose the monitor for a long time in direct sunlight, if
there is a touch faulty, please shutdown and restart.
4. After using, please clean the instrument and load it into special box, please place the parts into
the corresponding position, do not crush the screen.
5. The instrument should be placed in a cool and dry space.
6. Please do not disassemble the instrument, this will cause the instrument data errors or system
crashes.

Working Principle
Geophysical exploration is detecting stratigraphic rocks, geological structure and
other geological conditions through the study and observation of changes in a variety of
geophysical fields. commonly used geophysical exploration methods include gravity
exploration, DC exploration, alternating current survey exploration, magnetic
exploration, sonic exploration, seismic exploration, radioactive exploration, At present,
the m
ain geological exploration instrument is
electricity exploration in the market. And most of the instruments with features of
complex operation, heavy weight, too complex post-data processing, The users must be
many-year experienced technician who have to be professionally trained before the
operation of electricity exploration instrument.

detector is the latest product which research and development by our institute, using a
number of patented technologies.
The instrument is light and easy to carry, the length of measurement line need only 5-
10 meters, only one person can complete the operation, saving manpower and time, full
touch LCD screen,,
Simply operation, external insert a large-capacity memory card, the instrument w

wiring direction & Location
Geophysical lines are generally arranged perpendicular to the line to be constructed , can
detect tectonic crushed zone on both sides of the border and its different physical
characteristics , contrast is strong, crushing width , extending distinctive characteristics.
In order to accurately locate, confirmed the location of the abnormal ground point,
generally use measuring rope ( or tape ) pull straight line, and mark with paint at the
beginn
ing of the measuring line, so that find、 measure position according to the test
results of drawing later. The collected data each time is the data of midpoint between two
electrode data, the point O is the first set of data as shown below in figure 16. Electrode
spacing is generally 5-10m ( Choose 6/8/10m according to your actual situation), dot
spacing is generally about 0.5-2m, electrode spacing and dot spacing must keep the same
distance for one measuring line.
