RESECS DC-Resistivity and Electrode Control System
RESECS is an electrical survey instrument designed for high-resolution tomography and monitoring.
Up to 960 electrodes can be connected to the device using one seven-wire cable. Any pair of electrodes can be selected as a transmitting, and up to 8 other pairs can be selected as potential pairs for simultaneous measurement.
The software permits to switch quickly between pairs of electrodes, which ensures high speed measurements (up to several hundres thousand measurements per hour).
RESECS automatically selects all programmed array configurations. The system optimizes input current and gain, corrects for natural field values, and displays a real-time pseudosection and plot of current and voltage over time.
The system is well suited for long-term monitoring.
