Chapter 2: Installation
6. The first person applies 2 kg (4.5 lb) of pulling tension to the center conductor
with the pliers while maintaining a firm grip on the cable's black jacket.
Note: Maintain a firm grip and consistent pulling tension, and keep the sensor
cable taut and in-line with the second person during the center conductor
loosening procedure.
7. The second person picks up the sensor cable near the first, and waves it up
and down a few times creating small waves, which travel approximately 3 to 5
m in both directions along the cable.

8. At the same location, the second person taps the cable with the handle of a
screwdriver a few times, and then repeats the waving.

9. Move along the sensor cable, waving, tapping, and waving the cable at one
meter intervals. Continue waving and tapping until you reach the end of the
cable.
10. When the second person reaches the end of the sensor cable, the first person
releases the tension on the center conductor at the other end.
Part 2 - cable flossing:
Pull the cable by the outer jacket to remove any slack and then use a "flossing"
motion to pull the center conductor back and forth to ensure the center conductor
is floating freely over the full length of the sensor cable.
Initially, there may be resistance as well as some "stretching" as the center
Note:
conductor is freed inside the cable (i.e., the center conductor pulls out at one end
but remains the same length at the other). Once the center conductor moves
back and forth so that pulling it out 15 cm at one end causes it to retract 15 cm at
the other end, the conditioning is complete.
