FILTER
The XLT-17 has four different filtering modes.
AL (All Frequencies) – This is the No Filter feature of the XLT-17. No
modifications to the audio can be made with the arrow keys. Frequency
range of the All Frequency setting is from 60 Hz to 6 kHz. This mode is often
used to begin to listen for the leak noise.
(The following filter modes are often used to pinpoint the location of the
leak noise.)
HI (High Range) – This filtering mode allows the user to adjust the
response in the higher areas of the frequency range. Use the arrow keys
to increase or decrease this frequency response range.
LO (Low Range) – Similar to the previous filter mode, the lowpass
filter allows the user to listen to the lower areas of the frequency range.
The arrow keys are used to increase or decrease this frequency response
range.
FC (Frequency Choice) – This filter could also be called Frequency
Select. This mode allows tuning to the frequency that gives the user the
best audio response to the leak noise. The arrow keys are used to move
the cursor, selecting a narrow frequency band of choice.
