3. Erect the tripod above the borehole, and run the yellow
retaining tape through the loops. Fasten together the ends of the
tape.
4. The lifting cable is supplied with a loop at one end. Run this
over one of the pulleys at the top of the tripod, so that the loop
hangs down between the legs. If the loop is not provided, you
can make one by untwisting three outer strands from the (7-
core) cable, crossing the two sets, and pleating the three outside
strands back around the remaining four in the opposite
direction. Secure the loop with a cable clamp.
5. Run the sensor signal cable through the other pulley. Secure
both cables in their pulleys by sliding the attached bolts into
place.
6. Extend each of the three legs in turn to the height you require,
