ABEM Terrameter SAS 1000 / SAS 4000

Note!
Moisture and/or dirt in the connectors may compromise
the data quality and even cause permanent damage to the
connectors. Always keep the protection caps clean and in
place whenever possible. Let the protection caps protect
each other when the cables are connected as shown in the
picture.
Interconnect the Terrameter and Electrode Selector using the cable 33 0020 11 (alternatives as
per paragraph 6.1.3). Turn on the SAS 1000 / 4000.
At the second measurement station, and all the following stations as long as the line is being
extended, all four cables are connected (see Figure 11). Cable 1 is connected to Cable 2 with a
cable joint as well, where again the groove must face the cable closest to the instrument.
When finishing the measurement profile, and no additional electrode cable and electrodes are
put out, the instrument should still be moved one step in order to get all the near surface
information. The active electrode cables will thus be Cable 1, Cable 2 and Cable 3 (see Figure
12). Since all (for e.g. Wenner, Schlumberger and multiple gradient array) or many (for
dipole-dipole or pole-dipole) of the possible measurements have already been done for the
long layout protocol the measuring will be fast.
