You will then hear 2 beeps followed by a long 6-second tone, indicating that the first calibration point is found. 6. During the 6-second tone, raise the receiver straight up, keeping it level and in the same plane above the transmitter, as high as you comfortably can.

    ® Receiver Calibrating with Transmitter Underground at Shallow Depth (< 10 feet) Should recalibration be necessary when the transmitter is below ground at depths less than 10 ft (3 m), it is possible to conduct a modified 1-point calibration procedure. This requires knowing the signal strength of the transmitter in the housing at 10 ft.

  • Page 25: Finding Firmware Version

    It is possible to determine the firmware version in the receiver. This information is necessary to complete troubleshooting diagnostics with DCI Customer Service by telephone. At start-up the firmware version is displayed briefly in the top left window. If you do not see the firmware version, it is likely that you have an older receiver.

  • Page 26: Procedure For Observing The Predicted Depth

    ® Receiver Procedure for Observing the Predicted Depth When the receiver (with 5.0 firmware) is at the FNLP and held level with the trigger in, the bottom window will rapidly flash the predicted depth number accompanied by a solidly lit squiggle (“~”); the predicted depth information is also displayed in the bottom window on the remote display.

    DigiTrak Transmitter Specifications table at the end of this section. NOTE: The range of any transmitter with any DCI receiver is dependent upon the amount of inter- ference at a job site. The range decreases as interference increases.

  • Page 28: Batteries

    Batteries All DCI transmitters (except the cable transmitter) are powered by C-cell alkaline batteries (see Trans- mitter Specifications at the end of this section). The long-range transmitters, including the sensitive-pitch transmitters, have a 4 C-cell option for longer bores.

  • Page 31: Locating The Transmitter

    The sensitive-pitch transmitters are designed for gravity sewer installations where pitch must be known in increments smaller than 1%. DCI’s sensitive-pitch transmitters operate exactly the same as regular-pitch (1%) transmitters except that the pitch is measured and displayed in one-tenth percent (0.1%) increments.

  • Page 32: Serial Numbers

    All transmitters are identified by a serial number stamped in the metal battery compartment near the plastic/stainless steel contact. NOTE: When calling DCI Customer Service be prepared to supply the serial number. Specifications The specifications given below assume the use of the latest model (Mark III) of the DigiTrak Receiver. All Mark III Transmitters operate at a frequency of approximately 33 kHz.

  • Page 33: Remote Display System

    All receivers can be upgraded to remote capability by DCI. The maximum separation between the receiver and the remote display can range up to about 4000 ft (1220 m) depending upon interference and topographic features.

  • Page 43: Signal Interference

    Active interference is also known as electrical interference or noise and can have varying effects upon the DigiTrak locating equipment. Most electrical devices emit signals. Because DCI receivers have two types of antennas in them (depth and roll/pitch), it is possible to have interference that affects one or both signals.

  • Page 44: Suggestions For Dealing With Interference

    ® Signal Interference There are two steps to the electrical interference/background noise check. The first step takes one person; the second step requires two people. 1. With the transmitter off, test the amount of noise the receiver hears by holding in the trigger and walking the borepath from the launch to the exit location.

  • Page 45: Operational Tests

    5. An error code of “001” indicates high background noise; move to an interference-free area and con- duct the self-test again. For assistance with troubleshooting an error code call DCI. Receiver Balance Check If the receiver appears to be exhibiting a consistent left or right error, it is possible that the antennas in the receiver are out of balance.

  • Page 46: Receiver Gain Test

    Walk back toward the axis line from this opposite side and find the location where the “+” changes to a “–”. 5. These two locations should be in the same place and lie on the axis line. If not, call DCI for assistance.
  • Page 47 If not, check for interference, verify the transmitter’s signal strength, or call DCI Customer Service at 425-251-0559 or 800-288-3610 for assistance in determining the source of the problem.

  • Page 48: Transmitter Salt Water Range Test

    ® Operational Tests Battery Life – Verify the housing slots (windows) are properly aligned over the transmitter’s antenna. If the battery life of a transmitter seems to be shorter than that noted in the specifications provided in the Transmitter Section, it could be due to battery arcing, which can occur in hard drilling conditions. transmitter batteries arc when they bounce/slam into each other, losing contact intermittently.

  • Page 49: Transmitter Battery Tests

    ® Operational Tests Transmitter Battery Tests The design of the windows/slots in a housing can greatly affect the transmitter’s battery life, especially on the red long-range DX Transmitters. The windows must be a minimum of 8 inches (20 cm) long and line up longitudinally along the drill housing, directly above the center of the transmitter.

  • Page 52: Handling The Receiver

    ® Locating Handling the Receiver For the most accurate locating, the receiver must be held level and parallel to the transmitter. The receiver Receiver parallel to Transmitter and facing in opposite direction can be held so that it faces in the same direction as the transmitter or in the opposite direction (see sketch).

  • Page 53: Using Plus/Minus Indicators For Locating

    ® Locating In summary, the three locations mentioned above are as follows: the rear negative locate point (RNLP), behind the transmitter; the positive locate line, above the transmitter; and the front negative locate point (FNLP), ahead of the transmitter. The RNLP and the FNLP show the position and lateral orientation of the transmitter.

    ® Locating 2. To determine the lateral and therefore the actual location of the RNLP, turn toward the left so that the receiver is perpendicular (90°) to the drill string and move the receiver forward. Again, move the receiver slightly forward and backward until pinpointing the location where the “+/–”...

  • Page 56: Finding The Transmitter And Its Depth

    ® Locating Finding the Transmitter and Its Depth 7. While standing on the FNLP facing the drill, it is possible to “sight in” or align the FNLP with the RNLP. This axis line is at a 90° angle (perpendicular) to the PLL. Where this axis line crosses the PLL is where the transmitter will be found, below ground surface.

  • Page 57: Locating The Transmitter From The Front

    ® Locating Locating the Transmitter from the Front The transmitter’s three locations can be determined in a similar manner as described above starting in front of the transmitter while facing the drill. Start at a location well ahead of the transmitter and hold in the trigger while facing the drill. A “+” sign should appear in the top left window (along with the signal strength).

  • Page 58: Locating On The Fly

    ® Locating Locating on the Fly Once you are comfortable finding the transmitter’s three locating points (FNLP, RNLP, and PLL) it is time to increase your speed at locating. Hopefully this will directly affect your productivity! 1. Mark the position of the FNLP and pace out the distance of the next drill rod (this distance will vary depending upon the pitch of the transmitter and the topography).

  • Page 59: Splitting The Front And Rear Negative Locate Points

    ® Locating 4. Step further to the side of the transmitter and again find the point where the “–” sign changes to a “+” (Point 2). 5. Repeat this procedure to find the third location (Point 3). When all three of these points are lined up, they confirm the location of the PLL, from which the heading of the transmitter can be determined, because the PLL is at a 90°...

    ® Locating Running off Pitch or Calculating Depth from Pitch The transmitter’s depth can be estimated by using the pitch information. Use the following procedure to estimate the depth based on the pitch, starting with the first rod. 1. At the point the drill head penetrates the surface of the ground to the middle of the transmitter’s slots (entry point), measure the amount of rod left on the rack (from the make-up/breakout clamps to the top of the rod).
