10.6 Software & Communication
Terrameter LS is controlled using the incorporated Firmware. It supports Multi-
Electrode Survey Systems for 2D & 3D for Resistivity, IP & SP Imaging &
Monitoring.
It has a Graphical User Interface that is easy to follow in all its aspects. Clear and
instructive graphics assists the user in the operation of the instrument.
For enhanced Data Quality Control in the field it is possible to display the measured
Multi-Electrode Resistivity Imaging data in near real time as a pseudo section. Thanks
to access points as USB and RJ 45 (for LAN) transfer of data to other computers is
extremely simple.
For full inversion of data external software is required. Most common today is
RES2DINVor RES3DINV. This program supports data formats provided with the
help of the Terrameter LS software.
