1. Control Box
All listening and ltering controls for the XLT-30 are contained in this sturdy
housing. The function of each control is described in the section entitled
“Faceplate and Controls”.
2. Big Foot Sensor - OPTION A
Also known as the Ground Microphone, this sensor is to be used on hard
surfaces, concrete, asphalt, tile, etc. A fl exible rubber shield helps pre-
vent outside sounds from interfering with the sounds from the buried pipe.
Press and hold the red button near the handle to mute the audio from
the probe and suppress loud sounds when the probe is moved.
2A. Little Foot Assembly - OPTION C
About the size of a computer mouse, this small handheld sensor is de-
signed for areas that the Big Foot Sensor can not t into. The Little Foot
assembly is normally used for leak detection inside buildings. Mute is
activated by pressing the button in front of the Little Foot Assembly.
2B. Multi-Sensor - OPTION B
Fisher’s new MULTI-SENSOR has superior leak detection capabilities. In an
extremely compact design, Fisher has achieved higher performance,
improved audio clarity, improved sensor electronics, and better sensitivity
to leaks with less background noise – all with heavy duty characteristics
of the trusted Big Foot. The MULTI-SENSOR is used for both the ground
microphone and direct contact applications – the one sensor that does
it all. Fisher’s NEW XLT-30 MULI-SENSOR combo sets the new standard for
leak detection.
3. Hydrophonic Cylinder Probe
This probe is a direct contact probe designed to make direct connection
to the pipe, or any portion of the pipe that is accessible. Used in any
combination of Sound Rods with the T-Handle, pipes can be accessed
to distances up to nearly 6 feet away.
Another feature of the Cylinder Probe is the ability to listen to pipe noise
in pipes that are buried in turf, or soft surfaces. Accurate pipe location
is essential for the placement of the Ground Rods as close to the pipe
as possible.
On top of the Cylinder Probe is a three position toggle switch for mute,
listen, and momentary listen. As with all mute controls, learn to use them
wisely.
When tightening the sounds rods to the Hydrophonic Probe, secure the
connector with a wrench as to not let it twist. Twisting of that connector
could damage wiring on the inside of the probe.
