OPERATING INSTRUCTIONS
Set Up
1. Assemble control housing, headset, and Multi-Sensor. The headset
must be plugged in for the XLT-17 to operate.
2. Familiarize yourself with the location of the mute keypad.
Remember to mute the XLT-17 when moving any sensor.
3. Press POWER keypad to turn on the XLT-17. The XLT-17 goes through
a five second warm up before the touch pads are functional. During
this time, the display screen gives information of battery level. A battery
reading under 5 volts will activate the “Low Battery” indicator. The XLT-17
allows some time between the “Low Battery” indicator and complete
system shut down to allow you to complete a job.
4. The XLT-17 always turns on to the last settings used.
5. Press the VOLUME arrow keys to modify headset volume. Use the AR-
ROW keypads to increase or decrease the volume. The display screen
will show the volume level in a graph form.
6. Begin your leak detection search.
Modifications During Leak Search
Some leaks are small in size, and unrecognizable, or conditions are such
that very little leak sound can be recognized, so you may need to make
changes to the filter(s) in order to hear leaks. Depending upon the type
of pipe composition and soil (ground) type, different filter settings will
increase your ability to hear the leak sound.
Adjustment to the filter is done by pressing the FILTER keypad which will
allow you to scroll through four different filter types. Frequency range
modifications can be made to the HI, LO, and FC filters. As you are
choosing your filter, the display screen will give a visual display of the
filter type being used, and the frequency range of that filter. After your
selection and modification is made, theunit will automatically return to
the operating mode after a 5 second delay.

INSTRUMENT SET
1. Control Box
All listening and filtering controls for the XLT-17 are contained in this sturdy
housing. The function of each control is described in the section entitled
“Control Panel.”
2. Multi-Sensor
Fisher’s MULTI-SENSOR has superior leak detection capabilities. In an
extremely compact design, the MULTI-SENSOR provides better sensitiv-
ity to leaks, improved audio clarity, improved sensor electronics, and
less interfering background noise. The MULTI-SENSOR is used for both the
ground microphone and direct contact applications – the one sensor
that does it all.
3. Sound Rods
Two different sizes are included with the XLT-17. Rods give the user vari-
ous lengths for direct or indirect contact to pipes.
4. Multi-Sensor Handle
This handle is used with the Multi-Sensor
5. Sensor Cable
This cable attaches at the back of the Control Housing to any of the vari-
ous sensors, including the Multi-Sensor. Make sure the jack is fully inserted
and the lock nut is hand tightened.
6. Headphones
These headphones are designed to deliver the clearest sound with the
least distortion. The Volume knob can be used to adjust the audio level.
Unplugging the headphones will turn off the XLT-17. (When the XLT-17 is
turned off, any modifications to the Volume and Filter will remain at last
settings.)
7. Carrying Strap/Housing Mounting Bracket
The attachment system for the XLT-17 consists of a plastic mounting
bracket that slides from the bottom of the control housing up to the bezel
around the faceplate. There are two slots for attaching an adjustable
strap that hangs around the neck of the user.
