5.4.2 Information Display
At the top of the correlation display is an information display; some of the icons on the display also
show at the top of other screens.

Description
A
Save data icon
B
Correlation elapsed time indicator
C
Current Velocity. If a multi-section pipe model has been selected this display will
show “Multi”.
5.4.3 Start/Stop Correlate Button
To start a correlation, tap the Start Correlate Button. This button will automatically update to become
the Stop Correlation button. Whilst a correlation is running, the elapsed time will be shown in the top
left of the screen and will increment in seconds. A correlation can continue for a maximum of 5
minutes. If the Stop Correlate button has not been tapped before 5 minutes has elapsed the
correlation will stop automatically. To show that the correlation is currently in progress a play icon is
shown at the top of the screen. The elapsed time and play icon are still visible when the display is
swiped to the Controls or Frequency Spectrum screens.
5.4.4 Goto Peak Button
Tapping this button will move the cursor to the highest peak as determined by the software. The
distances displayed under the pipe model will give an estimate of leak position from each transmitter.
Use the left or right keypad buttons to move the cursor manually.
“Out of brackets” indicates the correlation peak is at
or beyond one of the sensor positions. Most likely
the pipe model has not been entered accurately, or
the velocity being used is incorrect. Check the
accuracy of the measurement of the pipe model
and then perform a Velocity Correction.
5.4.5 Noise Suppression Button
If an area of excess noise is shown on the correlation display it can be suppressed. This could be a
known noise from water consumption, a valve, flowmeter etc.
5.4.5.1
Turn Noise Suppression On
To suppress an area of noise tap the Noise Suppression Button, the button will turn yellow to show
noise suppression is active. To position the area of noise suppression, touch the screen in the
required location, and drag over the noise. The suppressed area will be shown in grey. Only one noise
suppression area can be active on each correlation.
5.4.5.2
Turn Noise Suppression Off
To turn off noise suppression tap the Noise Suppression Button, the grey highlight will disappear and
the noise suppression button will return to the blue off indication.
