  • Page 44: Sweep Locating Techniques

    Sweep Locating Techniques Overview There are two methods of passive locating, sweeping and line locating. Large Area Searching ‐ Peak Mode Description Depending on the specific sweep (Twin Peak), there is an available antenna selection. A traditional Zigzag approach is needed to detect and locate utilities crossing or running parallel within the search area.

  • Page 45: Radial Sweep Search

    Radial Sweep Search Description A 360-degree radial or perimeter sweep is a very efficient way to identify any signal paths associated with buried utility lines within your work site. Tra- ditionally the Transmitter is used in induction mode, but the technique should be used and adapted when a live connection can also be made.

  • Page 46: Induction Sweep

  • Page 47: Line Locating Techniques

    Observe the minimum distance of 6 m separation required to avoid airborne signals. Keeping the DT100 Locator vertical, set the initial locate parameters and walk along the line away from the Transmitter. Use a side-to-side motion with the Locator. Maintain the gain bar peak response within the green section.
  • Page 48 Orientation of the line is confirmed with the compass tails aligning with the target line. Match these vertically with the handle of the Locator and easy line locating should be achieved. As the distance increases between Locator and Transmitter, then it may be necessary to adjust the transmitter output to maintain the locate.
  • Page 49 Line locating in peak modes When line locating in peak modes, the Locator can be turned 90 degrees on its axis. This also helps the user to confirm orientation of the target line. Line locating in Tri-axial modes In Tri-axial modes, Sweep and Twin sweep, target line orientation does not matter in respect of the Locator orientation.

  • Page 50: Utility Locating - Active Signal

    Description Active locating uses a Transmitter to apply a DEDICATED ACTIVE FREQUENCY to a target line. The DT100 Locator is then used to detect the applied active signal flowing along the target line. Active location frequencies can be applied by direct connection with connection leads, induction or signal clamp.

  • Page 51: Direct Connection

    To inject a signal requires the use of a Transmitter. The Transmitter signal can be injected or applied to the target line in a variety of ways. Direct Connection • Refer to 9.1.1 Direct Connection for details Induction • Refer to 9.1.2 Induction for details.
  • Page 52 Start with a low output strength and increase if needed so that the locate parameters are met and signal current can be mon- itored. ☞ Setting the output too high or at the wrong frequency when it is not required may result in some of the active signal coupling onto other conductors.

  • Page 53: Induction

    When powered on, the Transmitter emits a frequency regardless of the Transmitter location. These signals penetrate the ground and couple onto buried lines. The signal then travels along the line which can be detected by the DT100 Locator. 9.1.3 Induction Nulling Out...

  • Page 55: Depth And Current Measurement

    Depth and Current Measurement Overview The DT100 Locator has depth and current measurement capabilities, which help users determine the depth of a target line. 9.2.1 Depth Description Auto depth estimation allows the Locator to calculate the approximate depth of the buried cable. This is typically done by analysing the strength of the electromagnetic signal emitted by a cable or transmitted signal as it passes through the horizontal aerials using an in-built algorithm.

    11.3 Setup Procedure Follow instructions for installing sonde battery. Turn on Locator to ensure that sonde is functioning properly. Attach sonde to drain rods, flex rod or similar. Place sonde into the pipe and move it down the pipe. Set operating mode to sonde mode in desired frequency. Locate sonde using peak and null methods.
  • Page 62 Pinpointing the sonde Once the peak sonde signal has been identified, orient the Locator so that the sonde icon is horizontally displayed on the crosshair. Move the Locator forward/back to obtain the strongest signal to pinpoint and locate the sonde. When the peak signal is found, place the foot of the locator on the ground.
