Safety Precautions
and Warnings (Cont.)
¾ Interference can cause significant inaccuracies in the measurement of depth and the TensiTrak
unit’s range capability.
• Sources of interference include but are not limited to traffic signal loops, invisible dog fences,
cable TV, power lines, fiber-trace lines, metal structures, cathodic protection, transmission
towers, cellular phones, telephone lines, conductive earth, salt water, rebar, and radio
frequencies.
• Interference with the operation of the remote display may also occur from other sources
operating nearby on the same frequency, such as car rental agencies using their remote
check-in modules, other directional drilling locating equipment, etc.
¾ During pullback, if depths are being tracked, they will not be accurate unless:
• The Eclipse receiver has been properly calibrated and the calibration has been checked for
accuracy so that the receiver shows the correct depth.
• The TensiTrak unit has been located correctly and accurately and the receiver is directly
above and parallel to the transmitter in the tool underground.
• The receiver height-above-ground or ultrasonic distance has been set correctly.
¾ The TensiTrak unit is positioned behind the reamer, between the swivel and the product so that
the TensiTrak unit does not rotate.
¾ Exposure to extreme vibration could possibly damage the TensiTrak unit and/or the batteries and
possibly reset the recorded maximum pull force.
¾ Exposure to downhole fluid pressures above 127 psi (876 kPa) could possibly damage the
TensiTrak unit.
¾ The TensiTrak unit should never be shrouded with a metal pipe, if a shroud is required, it must
be a nonmetallic shroud.
¾ Avoid pressure washing directly into the mud pressure sensor.
¾ Do not weld on the TensiTrak unit.
¾ Carefully review this operator’s manual and be sure you always operate the Eclipse TensiTrak
system properly to obtain accurate pullback, pressure, and depth data. If you have any questions
about the operation of the TensiTrak system, please call DCI’s Customer Service Department at
425-251-0559 or 800-288-3610.
REMEMBER: If you are having difficulty on the job, call DCI (425-251-0559 or
