FISHER XLT-30A Acoustical Leak Detector

FISHER XLT-30A Acoustical leak detector Version A: With the Big Foot Probe 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. Kit also includes: 1. 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. 2. Sound Rods Two different sizes are included with the XLT-30. Rods give the user various lengths for direct or indirect contact to pipes. 3. T-Handle This handle is used primarily with the Cylinder Probe and the sound rods. 4. 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-30. When the XLT-30 is turned off, any modifications to the Volume, Notch, and Filter will return to the factory presets. 5. Probe Cable This cable attaches at the back of the Control Housing to any of the various probes. Make sure the jack is fully inserted and the lock nut is hand tightened. 6. Carrying Strap/ Housing Mounting Bracket The attachment system for the XLT-30 consists of a plastic mounting bracket that slides f rom the bottom of the control housing up to the bezel around the faceplate.
