1 INTRODUCTION
This manual describes the Metrotech Model 9800XT Utility Line Locator. Included is an
equipment description, product specifications, checkout procedures, operating
procedures, application information and maintenance instructions.
The Model 9800XT is a series of state-of-the-art utility line locators precisely designed
with many powerful features to provide you with optimum information about your locate
situation.
2 SAFETY PRECAUTIONS
1 Metrotech Utility Line Locators are intended for use by utility and contractor
professionals. Safety hazards for underground utility access areas include
electrical shock, explosive gases, and toxic fumes as well as potential influence
on communications and control systems such as traffic control and railroad
crossings.
2 Familiarize yourself with all required safety practices of the local utility company,
or other owner of the plant before entering an access area or connecting a
Metrotech transmitter.
3 Before connecting the transmitter directly to any conductor, make sure that the
line is de-energized and out of service. Never make a direct connection to a live
power cable.
4 If you use the Metroclamp on energized electrical or control lines follow
appropriate safety procedures to avoid the risk of injury.
5 Pay special attention when using a locator in high traffic areas.
3 9800XT QUICK START GUIDE FOR THE EXPERIENCED USER
1 Check Batteries – Turn Transmitter to “L”. If the battery status is low (less than
5 bars) replace or recharge the battery. Turn Transmitter “ON”. Check battery
status. If low (less than 1 bar) replace or recharge batteries. CAUTION: Do
NOT attempt to recharge non-rechargeable D-cell batteries. Damage to the
transmitter will occur.
2 Connect Transmitter to Conductor - Turn Transmitter “OFF”. Plug the
Conductive Attachment into Transmitter. Clamp red lead to target conductor.
Stretch black lead 90 degrees away from conductor. Push ground rod into the
earth. Clamp black lead to grounding rod. Turn Transmitter “ON”. Select power
output and frequency.

Page 7 of 45
3 Adjust Receiver Controls - Turn Receiver “ON” and select frequency. By
default, the unit will operate in “Auto” gain mode.
4 Sweep Area Around Transmitter – Circle Transmitter with Receiver at a
distance of 10 feet (3 m). Left/Right display and Receiver signal strength will
indicate location of buried conductors.
5 Locate Line - Follow your target conductor, sweeping left and right as you walk
away from the Transmitter. Mark the centerline on the ground.
6 Measure Depth - Hold the Receiver over the centerline and push the depth
button. The LCD will display the depth and current measurement.

4.6.2 Receiver Features
Distance Sensitive Left/Right Guidance™ -Provides visual and audible direction and
distance information to guide you to the conductor.
Peak Mode – Provides a curtain display of the signal strength to locate the cable by
maximum signal strength instead of Left/Right Guidance. This mode is useful in special
applications and provides additional capability to the user.
Current Measurement - Doesn’t vary with depth, assists in positive line identification,
and helps identify T’s and laterals, large faults and holidays.
Battery Level Display - Continuously displays remaining battery life and provides
flashing low power alert.
Push Button Depth - Provides depth measurement in feet and inches (or in cm) in both
active and passive modes.
Real-Time Continuous Gain Adjustment™ - Automatic gain continuously optimizes
the sensitivity of the Receiver in a fully automatic way and eliminates the need for any
user adjustment.
Manual Gain Control - Provides higher sensitivity in particularly tough locate situations.
Dedicated gain up/down buttons provide maximum efficiency.
Simultaneous Peak and Null Display™ - Provides information on peak signal and
centerline simultaneously.
Battery Saving Automatic Power Down - After five minutes of no activity, the Receiver
shuts down to save battery life. Imminent shutdown is indicated by a warble tone. To
prevent shutdown, push any button while the tone is warbling.

Page 18 of 45
Depth Measurement to 20 Feet (6 m) - Depth measurement range is up to 20 feet (6
m) to provide information for deep locates.
RS232 Serial Communication Port - Provides data transfer capability for calibration
and service.
Not mention conversion of 50Hz to 60Hz until works on 9890XT?
5 CHECKOUT PROCEDURE
To ensure proper operation of the Model 9800XT Utility Line Locator, use the checkout
procedure below at the following times:
• upon receiving the equipment
• before each job, preferably before you leave for the site
• if problems arise during a locate
1 Turn the Transmitter “ON” and place it on the
ground. Note battery charge status at power up.
If charge is low, replace or recharge Transmitter
batteries. CAUTION: Do NOT attempt to
recharge non-rechargeable D-Cell batteries.
Damage to the Transmitter will occur.
2 Transmitter bargraph displays two flashing arrows and speaker beeps every 5
seconds.
3 Plug conductive attachment leads into the
Transmitter, and attach them to one another. The
bargraph display should read less than 5 ohms
and maximum output level in high power setting. See Figure 5-1
4 Turn the Receiver “ON” and set to an active
frequency. Set Receiver to same frequency. Make
sure that Receiver is operating in “Auto” gain
control mode. Aim the Receiver at the Transmitter
and move it back and forth. The Left/Right
Guidance System display should respond. The
signal strength should also respond to the
movement and be at its highest when pointed
directly at the transmitter. See Figure 5-2.

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 of 45
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. A fast beep indicates the batteries are low. Turn the
Transmitter “OFF”. CAUTION: Do NOT attempt to recharge non-rechargeable D-Cell
batteries. Damage to the Transmitter may occur.
6.1.2 Hook the Transmitter Up - The three methods of applying the signal to the
conductor 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 conductor (hydrant, meter,
riser, valves, sheath, and tracer wire), allowing maximum signal to reach the conductor.
In this operating mode the Receiver can be closer to the Transmitter, and adjacent
buried conductor interference is reduced.
WARNING
Never make a direct connection to a live power cable. Always make sure the power
cable has been taken out of service, is fully discharged and grounded before you make a
direct connection to it. If you use the Metroclamp on energized electrical or control lines,
follow appropriate safety procedures to avoid the risk of injury.
1 Insert the Conductive Attachment - Turn the
Transmitter off. Plug the Direct Connect Cable
into the OUTPUT JACK on the Transmitter.
2 Connect to your conductor - Connect the RED
lead of the Direct Connect Cable to the targeted conductor.
3 Set up and connect to a ground - Extend the
BLACK lead of the Direct Connect Cable as far as
possible from the conductor, at a right angle.
Look for a convenient existing ground, such as a
metal street sign. Be careful not to get close to or
cross any adjacent buried conductors. If no
existing ground is available, use the ground spike.
Drive the ground spike as far into the ground as
possible, and attach the BLACK lead. If the
ground surface is too hard, place the ground plate
on the ground and attach the BLACK lead. To
