Resistivity
Equipment Description and Field Operation.
The 2D resistivity Survey was carried out
using a Syscal pro unit
Figure 2. Syscal Pro Unit
Other accessories used were:
· 24 Electrodes
· 24 Alligator clip cables
· A multi-core cable (60 to 70m)
· Laptop Computer
· RES2DINV computer Program
· Hand Auger
· Shovel
The survey was also carryout using 24 electrodes connected to a
multi-core cable which were also connected to a laptop computer. The spacing
between electrodes was 2.5 m for a total of 60 m. Before starting the test it
is necessary to set up the Syscal pro unit with certain parameters to be able
to obtain the desire data.
After entering the parameters, is important to choose the
electrode array. Dipole-
dipole and Schlumberge-Wenner arrays were used to measure
the resistivity of the area. After performing the test the data was send to the
computer to the file created before the test.
Dipole-dipole array, and the Schlumberge-Wenner
Array methods were used to collect the data.
