  • Page 22: Induction Method

    Connect the 3M™ Dyna-Coupler to the transmitter Output Jack [T-6] using the coupler cable (9011). Clamp the Dyna-Coupler around the cable or pipe, below any bonds, just before it enters the earth. The jaws of the coupler must fully close.
  • Page 23 B. Sweeping (Active) Induction Mode Locating Sweeping an area with the 3M™ Dynatel™ Advanced Locator 2200M Series allows the location of multiple metallic cables and pipes buried in an area without direct connect or coupler access to the cable or pipe.
  • Page 24 CATV signal of 31.25 kHz NTSC with CRT TV turned on. Active Sweeps: These require both the Receiver and Transmitter with Induction capability. This method refers to using a 3M™ Dynatel™ Advanced Locator Transmitter as the signal source through induction, instead of relying on passive frequencies that may exist on the buried conductor or metal pipe. Active Induction allows for detecting buried cables and metal pipes in the absence of passive signals and at deep depths and short sections.
  • Page 25 and orientation is key to maximize the induced signal in the buried cable or metallic pipe enough to be detectable by the receiver along each path in the swept area. (Note that no signal is induced onto a conductor whose path is perpendicular to the Induction Direction indication.) • Place the transmitter in the upright (bottom on ground) position for directional optimization when aligned with the Induction Direction shown on the label on the...

  • Page 26: Receiver Modes

    • Select the Induction Peak (IndPk) mode, and press the Gain (+ or -) until the bar graph is just visible. Sweeping • Sweeping can be done at close distances between the transmitter and receiver. • For best results, the receiver should be at least 7.6 m (25 feet) away from the transmitter to begin tracing the target path and have the gain set between 78-84% when starting the sweep. Attempting to trace the target close to the transmitter may lead to false indications due to the receiver detecting the large magnetic field radiating from the transmitter.

  • Page 27: Directional Null

    Once the target path has been located, the arrows at the top of the screen will indicate the location of the target path in relationship to the receiver. Note: When field distortion (due to congestion) is affecting the receiver the left/right arrows may not coincide with the bar graph. Use the maximum numerical signal strength to target the cable or pipe. B.

  • Page 28: Special Peak

    Left or Right of Target Path Directly Over Target Path D. Induction Peak (Ind Pk) If you cannot make a direct connection, or use the 3M™ Dyna-Coupler clamp to apply a locating signal on the target, use the induction method. This method uses the internal coil of the transmitter to generate a magnetic field. The Induction Peak mode of the receiver is a mode in which the upper antenna of the receiver is tuned to minimize distortion from the magnetic field of the transmitter.
