Page 19: Operation
Figure 5-1: Connect Transmitter Leads Figure 5-2: Aim Receiver at Transmitter 6 OPERATION Follow the Checkout Procedure described in Section 5 before operating the equipment. To operate the 9800XT Utility Line Locator use the Transmitter to apply the signal to the conductor, and use the Receiver to trace the signal from the conductor.
Page 20: Transmitter Set-Up
6.1 Transmitter Set-up 6.1.1 Check the Battery - Turn the Transmitter “ON” by turning the left knob to “L” (low). Battery status will be indicated by the number of bars on the LCD. 100% charge - 11-12 bars 50% charge - 5-6 bars 25% charge - 1-3 bars The audio tone will also indicate the battery status - a slow beep indicates the batteries are sufficiently charged.
Page 21: Figure 6-1: Direct (Conductive) Connection
improve conductivity, put water and/or a weight on the plate. See Figure 6-1. Select a frequency - The 9860XT Transmitter offers two active frequencies - 9.82kHz and 82kHz. The 9890XT Transmitter has three active frequencies - 982Hz, 9.82kHz, and 82kHz.

Page 23 Place an inductive Metroclamp around the conductor. The Transmitter clamps are available for use with the 9800XT. Metroclamp Ground Requirements - If you are using the Metroclamp around a cable, both ends of the cable must be grounded. This ensures a ground return path for optimum current flow (signal strength).
Page 24: Figure 6-2: Inductive Coupling With The Metroclamp
Figure 6-2: Inductive Coupling with the Metroclamp Turn the Transmitter to “L” - The Transmitter will first display battery life. Then the display will show blinking right and left arrows. Trace your conductor - Refer to Section 6.2 for tracing instructions. C Inductive (Indirect Method) - This is the least effective method of applying signal to isolate one conductor.

Page 26 Set the frequency - Turn the left hand knob to set the Receiver to the desired frequency. The selected frequency will appear in the upper right hand corner of the LCD display. If you are locating actively, you need to match the frequency to that of the Transmitter.
Page 27: Figure 6-4: Receiver Position For Tracing
Figure 6-4: Receiver Position for Tracing Distance Sensitive Left/Right Guidance - will visually guide you to your conductor. When the bar is to the left, move to the left. When the bar is to the right, move to the right. When you are centered over the conductor, the vertical bar will be centered between the arrows.
Page 28 Switching between automatic and manual gain control mode - To adjust the gain manually, push the ”Auto/Man” button once. ”MAN” appears on the display when in the manual gain control mode. Adjust the gain up or down using the red up/down arrow buttons.
Page 29: Figure 6-5: Receiver Position When Determining Depth
When determining depth in an active mode, the Receiver Left/Right Guidance System must be centered within 3 bars from the centerline in order to get a depth reading. If it is not, the unit will beep and display “CL” (center line) when you push the depth arrow button.
Page 30: Figure 6-6: Principle Of Triangulation
completely and the audible tone is continuous (gain is too high). Adjust the gain upwards pressing the red gain up arrow button if the “curtain” displays nothing and there is no tone (gain is too low). The selected gain setting will be indicated on the Receiver LCD display in the upper left corner.
Page 31: Figure 6-7: Receiver Position For Triangulation
Figure 6-7: Receiver Position for Triangulation Figure 6-8: Locate Centerline 6.2.5 Triangulation for Confirming Presence of Common Trench Conductors - If you are locating a conductor in a common trench, your signal may induce onto a more shallow or better conductor. When this occurs, you may get an unlikely depth reading using the Receiver push button depth measurement function.
Page 32: Advanced Techniques
Figure 6-9: Multiple Conductors in a Common Trench 7 ADVANCED TECHNIQUES 7.1 Ground Survey - Regulations at construction sites often require a ground survey before any excavation is done. This prevents damaging underground utilities. A ground survey is a process to locate all the underground conductors within a particular area. It includes standard locating and a blind search.
Page 33: Figure 7-1: Blind Search Parallel Pattern
Operator 1 holds the Transmitter at his/her side and level with the ground. Operator 2 holds the Receiver vertically at his/her side with the top surface of the Receiver facing the Transmitter. Walk together across the search area. The Receiver Left/Right and the signal strength reading will indicate the presence of a conductor under the ground as the operators pass over it.
Page 34: Adjacent Conductors
Figure 7-2: Adjacent Conductors - Position of Ground Lead Move Ground Away From PPE 7.3 Deep Conductor - Signals picked up by the Receiver from deeply buried pipes 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 35: Valves, Manhole Cover, T's And Risers
If you pivot all the way around (360 degrees), without getting any noticeable signal strength, it means you have reached a dead end. See Figure 7-5. 7.7 Valves, Manhole Cover, T’s and Risers - If the signal strength suddenly increases and then falls back while tracing a pipe you have probably passed over a buried valve, manhole cover, T, or riser.
Page 36: Common Bonded Conductors
Figure 7-5: Locating a Dead End 7.8 Common Bonded Conductors - Telephone, power, and CATV sometimes use a common ground bond. If other conductors are connected to your target conductor, putting a signal on the target can cause all the conductors to carry the same signal, making it difficult to identify the target conductor.
Page 37: Figure 7-6: Incorrect Coupling For Congested Area
Determine the location of the adjacent conductors. Then check to be sure that neither the direct connect cable or the ground cable cross over any of the adjacent conductors. Reposition them if necessary. If you are inducing, you can decrease the interfering signal by changing the position of the Transmitter.
Page 38: Determining If You Have A "Ghost" Conductor
Figure 7-7: Correct Coupling for Congested Area 7.11 Determining If You Have a “Ghost” Conductor - If there is another conductor near your target conductor, it too may pick up signal from the Transmitter. When this occurs, there will seem to be a ”ghost” between the two conductors. You are likely to have a ”ghost”...

to a ground spike at the end of a service, where the pipe or tracer wire comes out of the earth. Be sure to remove the ground connection after completing the locate so as not to defeat the cathodic protection system. 7.14 Non-Metallic Pipes - To trace nonmetallic pipe (sewer line) or duct, send the signal through the pipe by inserting the appropriate Metrotech Sonde (according to the operating frequency you are using).
