OPERATING INSTRUCTIONS
Set Up
1. Assemble Control Housing, Headset, and your choice of listening probe .
The headset must be plugged in for the XLT-30 to operate.
2. Depress POWER pad to turn On the XLT-30. The XLT-30 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 reading of
68 or below will activate the “Low Battery” indicator. The XLT-30 does
have a usage buffer between the “Low Battery” indicator and complete sys-
tem shut down to allow you to complete a job.
3. The XLT-30 always turns On to the default settings. Volume is at the
Medium setting, Filter is in the All Pass (no filter) mode, and the Notch
Control is at the Midway point. The display screen will show the sound
intensity in a bar graph form (Sound Graph) and two digit display.
4. Familiarize yourself where the Mute Buttons (and pad) are. Remember
to Mute the XLT-30 when moving any probe.
5. Depress the VOLUME pad to modify headset volume. Use the ARROW
pads to increase or decrease the volume. The display screen will show the
volume level in a graph form. Depress the RESUME pad to exit Volume
modification and return the Display Screen to the Sound Graph function.
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 depressing the FILTER pad 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, depress
the RESUME pad to return to the Sound Graph function of the
display screen.
