Current and potential connectors
For measurements utilizing only one channel (out of the four channels) it is often easier to use
the four ”banana” connectors labelled C1, C2, P1 and P2. These connectors are localized
above the instrument display. In cases where more channels are needed, the MULTI
connector has to be used. The C1, C2, P1 and P2 ”banana” connectors are connected in
parallel to the corresponding pins in the MULTI connector.
To connect more than one set of potential electrodes, use the Multi Channel Adapter (optional
accessory for the SAS 4000).

ACCESSORIES
2.6.1
The LUND Resistivity Imaging System
The LUND system is a multi-electrode system for high-resolution 2D and 3D resistivity
surveys. It consists of a basic unit, the Electrode Selector ES464 or ES10-64, and multi-
conductor cables. The system can be controlled directly from the SAS 1000 / 4000. Among
the powerful features you will find:
•
64 electrodes unrestricted switching in a compact, battery-operated unit.
•
Robust, waterproof design for reliable operation in harsh environments.
•
Designed to link to the Terrameter SAS 1000 / 4000 with one single cable.

connectors.
