Setting Up TensiTrak System
Before saving TensiTrak data on the Eclipse receiver, you must set up the system properly.
¾ You must confirm that the mud pressure sensor and battery cap on the TensiTrak unit are free of
damage and wear.
¾ You must power up the TensiTrak unit, the receiver, and the remote display.
¾ You must verify that the TensiTrak unit is sending data to the receiver and that the receiver is
transmitting this data to the remote display at the drill.
¾ If you plan to track the depth of the TensiTrak unit during installation, then you must calibrate the
receiver to the TensiTrak unit in an interference-free environment. You must verify your
calibration.
¾ You may need to change the job number on the receiver if this is not the first time the system is
being used.
¾ You must correctly connect the TensiTrak unit to the other components of the downhole
assembly.
¾ You must start the data saving mode to begin saving the TensiTrak data on the receiver.
TensiTrak Downhole Assembly
NOTE: It is extremely important to ensure that the TensiTrak unit is oriented correctly with the
direction of pull back. The mud pressure sensor must be on the trailing end.
Because the TensiTrak unit begins measuring and saving data once the batteries are installed, you may
prefer to power up the TensiTrak unit after it is positioned with the rest of the downhole assembly near the
pull-in area.
NOTE: If you remove and replace the TensiTrak unit’s batteries when it is under load, the pull
force measurements will not be accurate because the TensiTrak unit “zeroes” the pull
force measurement at battery installation. If this occurs you must remove and replace the
batteries when the TensiTrak unit is not under load.
