MODES

Level Mode
(Default on power-up)
In this mode, the XLT-100 displays the sound/vibration level. No mode indicator is displayed in this mode.
VOLUME MODE
In this mode, the user can increase or decrease volume levels.
To enter Volume Mode, press the buttons when in Level Mode. The VOL mode indicator will be displayed.
The numeric display indicates the current volume level as a number between 0 and 99. After 1.5 seconds with no volume adjustments, the device will automatically revert to Level Mode.

FILTER MODE
To enter Filter Mode, press The FLT mode indicator will be displayed.
In Filter Mode, the user can select from 8 different boost/cut equalization filters with center frequencies at 500, 1000, 2000 and 4000 Hz. The boost filters emphasize frequencies around the center frequency.
The cut filters will de-emphasize frequencies around the center frequency. Alternatively, the user can select the all-pass filter, filter number zero, which is the default filter. To exit Filter Mode, and enter Notch mode, press .

NOTCH MODE
To enter Notch Mode, press until “NCH” is displayed. In Notch Mode, the user can select the 50 Hz notch filter, the 60 Hz notch filter or no notch filter. When using a notch filter the “notch” frequency will be filtered out.

MUTE
Turn off the volume by pressing
Use this mute function to protect your ears from loud sounds during set-up.

BACKLIGHT
Press to turn backlight on or off.

BATTERIES
The XLT-100 uses two AA batteries. Operating life using 2 AA alkaline batteries is approximately 12-15 hours. When charge indicator becomes low, batteries should be replaced. The XLT-100 will automatically turn off if the battery voltage becomes too low. To replace old batteries, use a coin or flat- head screw driver to turn the battery cap counterclockwise until it comes off. The XLT-100 has special foam inserts in the battery compartment; these inserts may prevent batteries from sliding out. If this happens, gently tap the bottom of the XLT-100 on
a flat surface, and batteries will dislodge.

EXTENSION RODS
Included extension rods (2-13”) May be used in place of standard probe tip when longer reach for contact with facility is required. Extension Rods can also be inserted into probe holes over water line in turf areas.

HAND NOISE
Like all accelerometers, contact microphones, ground microphones and stethoscopes, hand movement on the surface of the housing will induce vibrations into the sensor which you will hear as a rubbing noise. To avoid this, hold housing securely and do not move hand over the surface while listening.

SOME POTENTIAL HAZARDS
As the sensor and extension rods are “pointed”; caution should be used when operating or transporting the device.
Always select the lowest volume setting that is appropriate for each leak sound analysis.
It is recommended to set device to MUTE until positioned to sample for leak noise, then set to OFF or MUTE immediately after each sampling.
For safety reasons, do not use this device near traffic or where other dangers are present. This device is to be used with interconnecting cables/headphone cables shorter than three meters.
Fisher Research Laboratory does not warrant suitability to specific use. Fisher Research Laboratory shall in no event be liable for any direct, incidental, consequential or indirect damages.
