A programmable automated resistivity device was designed and
constructed. The device was created to perform near surface studies,
particularly archaeogeophysical target characterization. Field and
physical model studies can be performed changing the current input of
the device. The equipment consists of two independent devices, each one
with its own microcontroller platform. They are interconnected through
serial data transfer protocol. The first device, works as a
resistivimeter where the ABMN electrode positions are programmed and
permits the interaction with the user. The second one, connects the
current and voltage channels to the programmed electrodes positions.
Different targets and electrode configurations such as dipole-dipole,
Werner-Schlumberger and γ112 where tested in order to
verify the performance of the automated resistivity device. The
measurements give mean relative standard deviation values between 0.7%
and 3.7% and data inversion convergence between 2.6% and 11%.
