possible that, due to the limitations of this technology, the sound may be
received with a slight delay of about 0.1 seconds.

Leak Detection Cursor: Normally, it indicates the place of the ongoing measurements.
Every time the MUTE key is pressed and released, the minimum and mean signal data are
displayed in the form of bar or line-graphs at that point. Then the cursor points to the next
column.
The user can use the UP and DOWN keys to move the cursor and scroll between the
measured points too. In this case, the user can erase each point by moving the cursor to
the place of the desired point and pressing the DELETE key. The system shifts all data
frames to the left to keep the measurements continuous. Note that when the device is in
scroll mode, pressing the MUTE key will move the cursor to the end of the point sequence
where the next point is going to append to the sequence.
Please be advised that the deleted data cannot be recovered by any means;
therefore, please make sure you are always aware of where you move the
cursor and what operation is going to be performed next.
4-
Invalid Measurement: When the user presses the MUTE key, the sound is immediately
streamed on through the headphones. At the same time, a red bullet appears on the right
side of the screen, which indicates that the device does not collect the sufficient number
of data yet to calculate the measurements of received signals. Sudden pressings of the
MUTE key which store no data in the memory are eliminated from the data as the device
is programmed to intelligently detect the invalid data and refrain from saving or displaying
them.
5-
Valid Measurement: When the user presses the MUTE key and keep holding it for about
2 seconds, the red bullet disappears and is replaced by a green one. This means the
ongoing measurements are valid and the system is now ready to display the vertical bar-
graph as well as the minimum and mean received signals. As soon as the MUTE key is
released, the green bullet disappears.
6-
Signal Value Progress Bar: A horizontal progress bar is designed to show the immediate
value of the received signal. Considering this progress bar, the user can figure out in which
range the signal value is measured. Note that if the signal values differ too much from
each other, it may not be a good measurement.
7-
Graph Grade: The screen has been scaled on the vertical axis into grid lines ranging from
0 to 100 so that the minimum and mean received signal strengths can be displayed
analogously in the form of bar-graphs or line-graph.
8-
Bar-graphs: Every time the MUTE key is pressed and held, the user can listen to the
sensor’s amplified sound and the device measures these signals in high speed. As soon as
the MUTE key is released, the device displays the minimum and mean signal strengths
that it has during the time the key was held in the form of two bar-graphs, one blue and
the other white.
The blue bar graph represents the minimum signal (MIN) and the blue number under it is
its corresponding numerical value.
The white bar graph represents the mean signal (MEAN) and the white number under it
is its corresponding numerical value.
If the red bullet is displayed on the screen, the device is unable to calculate the minimum
and average signals and, thus, the data are not valid for calculations. The emergence of
the green bullet, however, indicates that the device can calculate and display the correct
MIN and MEAN values.
