To open the battery compartment door, turn the spring- loaded quarter and separate the compartment door by gently pulling on the latch.

  • Page 17: Checkout Procedure

    5 CHECKOUT PROCEDURE For proper operation of the Model 810Dx Pipe and Cable Locator, use this checkout procedure: • upon receiving the equipment • before each job, preferably before you leave for the site • if problems arise during a locate Place transmitter on the ground.

  • Page 18: Operation

    Figure 5-2: Aim Receiver at Transmitter 6 OPERATION Follow the Checkout Procedure described in Section 5 before operating the equipment. To operate the 810Dx Utility Line Locator use the Transmitter to apply the signal to the utility, and use the Receiver to trace the signal from the utility. WARNING Never make a direct connection to a live power cable.

  • Page 19: Figure 6-1: Direct (Conductive) Connection

    6.1.2 Methods of Applying Signal to a Utility - The three methods of applying the signal to the utility are - Direct Connect, Inductive Coupling, and Inductive. Following is a description of each method and instruction of use. A Direct (Conductive) Connection - This is the preferred mode of operation because the transmitter is connected directly to a metallic part of the utility (hydrant, meter, riser, valves, sheath, and tracer wire), allowing maximum signal to reach the utility.

    one utility. The signal is broadcast in all directions and can couple to every nearby utility through electromagnetic induction. It is possible to reduce the broadcasting signal by pressing the power output level button to change the power level from high to medium or medium to low. The transmitter induction antenna will be “ON”...

  • Page 22: Figure 6-4: Receiver Position For Tracing

    make sure the Receiver is not air coupled to the Transmitter. This can occur from 8 to 50 feet (2.5 to 15 m) from the Transmitter. To determine air coupling, find a centerline and lift the Receiver straight up. If the signal strength decreases smoothly, the receiver is not air coupled.

    button for 3 seconds. Turn Receiver OFF by pressing the ON/OFF DEPTH button for 3 seconds. Disconnect the accessories when you have finished your locate. 6.2.2 Determining the Depth of a Utility - The depth of a utility may be determined in any of the Transmitter hook-up modes.

  • Page 24: Figure 6-7: Receiver Position For Triangulation

    Centerline and record the depth by pressing the ON/OFF depth button. Mark the centerline Tilt the Receiver away from the utility at a 45-degree angle – Touch the horizontal antenna to the ground while the tip of the receiver on the ground Move away from the utility - The Left/Right Guidance System will indicate another centerline.

    conductive utility. Use triangulation to confirm the presence and depth of multiple utilities. Find the depth of the first utility and then continue to move away from the utility, marking each utility depth. Repeat the process to the other side and then calculate the depth of each utility. See figure 6-9.

  • Page 26: Adjacent Utilities

    move in parallel across and then down the survey area, parallel to one another. Operator 1 holds the Transmitter at his side and level with the ground. Operator 2 holds the Receiver vertically at his side with the top surface of the Receiver facing the Transmitter.

  • Page 27: Deep Utility

    Figure 7-2: Adjacent Utilities - Position of Ground Lead Move Ground Away From Pipe 7.3 Deep Utility - Signals picked up by the Receiver from deeply buried utilities are weaker and not as directionally distinct as those from pipes closer to the surface. In addition, the signal strength will only change by small increments in relation to moving the Receiver antenna.

  • Page 28: Common Bonded Utilities

    Figure 7-3: Locating Service Laterals Figure 7-4: Locating a Bend Figure 7-5: Locating a Dead End 7.8 Common Bonded Utilities - Telephone, power, and CATV sometimes use a common ground bond. If other utilities are connected to your target utility, putting a signal on the target can cause all the utilities to carry the same signal, making it difficult to identify the target utility.

  • Page 29: Congested Areas

    the utility and the Receiver. 7.10 Congested Areas - If you suspect that coupling from adjacent utilities is causing interference in the signal picked up by the Receiver, try increasing the strength of the signal on your utility and decreasing the strength of signal from the interfering utilities by: Changing to a different transmitter coupling point or coupling mode.

  • Page 30: Determining If You Have A "Ghost" Utility

    7.14 Non-Metallic Pipes - To trace nonmetallic pipe (sewer line) or duct, send the signal through the pipe by inserting the appropriate 83kHz Metrotech Sonde. For accurate depth readings with Sonde, refer to the sonde depth table to convert indicated depth to actual sonde depth. An alternative method is to insert a snake or fishtape into the pipe and connect the Direct Connect Cable from the Transmitter to one end of it.
