Electrode Selector / Lund Imaging System
To operate the electrode selector with SAS 1000 / 4000 the boxes must be interconnected by
the Multi-function cable, 33 0020 11. This applies for ES10-64e, ES 10-64 and ES 464
delivered after September 1997.
Older ES 464 units delivered before September 1997 will need two cables: one
Communication Cable for Electrode Selector to Terrameter, 33 0020 08 and one
Current/Potential Cable, 33 0019 17.
Special connection cables
These two cables are used instead of the multi-function cable 33 0020 11 (not applicable to
ES10-64):
•
In the normal setup, as described above, only channel one in the SAS 1000 / 4000 is used.
With an optional Pole-Pole cable, 33 0020 14 between the SAS 4000 and one unit ES 464
it is possible to perform pole-pole measurements using three measuring channels on the
SAS 4000.
•
With the optional Y-cable, 33 0020 15 it is possible to connect two ES 464 units to the
SAS 4000. This allows for e.g. dipole-dipole measurements with three channels on the
SAS 4000.

With 2 meter intervals between the electrode take-outs the system has a total length
of 160 meter, with 5 meter intervals the total length is 400 meters.
