4. Confirm or Change Job Number (Receiver)

You will need to use the Receiver’s Job Number command to assign a job number when you are starting

a new run. To change the job number:

1. From the Eclipse main menu, toggle right to select DataLog, then click the trigger.

2. Select Tension DataLog, then click the trigger.

3. Select Job Number, then click the trigger. The last job number that was used is displayed.

4. Push the toggle up to advance to the next run number, then click the trigger.

5. You will be asked if you are sure. Use the toggle to select Y for yes, then click the trigger.

6. The new job number will be shown on the screen.

5. Calibrate Receiver to TensiTrak Unit

If you are going to track the depth of the TensiTrak unit, then you must calibrate the receiver to the

TensiTrak unit. This should be done in an interference-free environment—that is, there should be no

passive or active interference sources within 10–15 ft (3–4.6 m) of the receiver and TensiTrak unit. When

you go into Tension mode you should see a stable signal strength in the bottom left corner of the screen.

NOTE: If depth readings are not needed, calibration is not required. Measurement of the pull

force and downhole mud pressure does not require calibration. The depth readings are

not saved.

NOTE: Calibrating the Eclipse receiver to the TensiTrak unit will erase the previously saved

calibration for the single-high (SH) mode. The Eclipse receiver will require calibration

when a different transmitter is used in SH mode.

Calibration and Verification Procedure

1. Using a tape measure, position the TensiTrak unit at a distance of 10 ft (3 m) from the receiver,

as shown in the figure below; measure from the centerline of the TensiTrak unit to the bottom

inside edge of the receiver (below the display window at the ground, not at the upper edge of the

display, which is wider). Be sure to position the TensiTrak unit with the pulling eyes “open to the

sky” (facing up and down) rather than with the pulling eyes on edge.
