ADS Eureka2R Leak Noise Correlator User Manual

Manual Velocity allows you to enter a value for velocity. This value replaces
the velocity obtained from tables. After entering this value through Mode >
Measure Velocity, it displays on the main Correlate screen. Once a value
has been entered, the button changes to Auto Velocity. Pressing this button
uses the default value from the tables.
WARNING: Velocity can vary with MDPE (medium density
polyethylene) pipes. Values listed in this table are theoretical and,
therefore, may cause errors in a practical situation. ADS strongly
recommends measuring actual velocity on site wherever possible.
Save
This function stores the result of a correlation, recalls a previously saved
result, and prints the displayed correlation.
The screen displays the correlation and identification details.
 Details This allows you to change the identification text. The three
fields include Identity, Site, and Operator.
 Save This stores the correlation in memory.
 Print This prints the displayed correlation to the printer. Normal
printer error messages, such as Out of Paper, display when necessary.

Files This opens a screen for selecting stored correlations. A list of
stored results displays. Scroll through the list using the up and down
arrow buttons. Delete or recall a selected file using the other buttons.
Since recalling deletes the data previously displayed, a warning will
display.
Vector Correlate
This is an advanced signal processing technique that improves correlation on
very low frequency signals, particularly in trunk mains and long plastic pipes.
However, use this option ONLY when normal correlations fail. It is
specifically designed for use with hydrophone sensors. The filters must be set
to the 3Hz – 100Hz band.
Adjust
The Adjust function allows you to set the screen contrast, turn on and off the
backlight, adjust the headphone volume and balance, and select the leak noise
filters.
