Prerequisites
The M3 software must be running.
TipMake sure there is sufficient disk space available to complete the survey.
Procedure
|
1 |
Click to start the Sonar Head.
Make sure that a sonar image appears in the sonar view window.
|
|
2 |
Click the “i” icon in the top-left corner of the sonar view to open the Information Widget.
Make sure that the sensor data is updating in the Information Widget.
|
|
3 |
Select Profiling from the Sonar Apps menu.
Note
The selection of sonar applications presented in the Sonar Applications menu depends on the current Sonar Head frequency.
|
|
4 |
If the profiling settings are not visible, click to open the Profiling Settings dialog box. |
|
5 |
Check the Depth Tracking box to automatically adjust the range according to the current depth. |
|
6 |
Make sure that data is displayed and being updated in the 3D Point Cloud window. |
|
7 |
Make sure that no errors are displayed in the Output Messages window.
|
b |
Make sure there are no errors shown in the Output Messages window under the Host Messages or Head Messages tab. |
|
|
8 |
Make sure there are no errors in the Connection Status and Head Status windows.
|
a |
Click on the text “Active” located in the lower-right corner of the status bar.
Observe that the Connection Status window opens.
|
|
b |
Make sure that all items listed under the M3 Sonar show check marks.
If any items are shown with an “X” in a red circle, it usually means the device has failed to connect. Disconnect and make sure that no sensors have failed.
|
|
c |
Click on the top line in the Connection Status window.
Observe that the Head Status window opens.
|
|
d |
Make sure that all parameters in the list are shown with a check mark inside a green circle. |
|
|
9 |
Make sure there is no acoustic or electrical interference in the sonar view.
|
A |
Make sure that no concentric rings appear. These rings could be caused by other acoustic devices or power-line noise. Rings with black gaps between them could also be due to excess Ethernet traffic when using a shared network. |
|
B |
Make sure that there isn’t a bright radial line originating from the Sonar Head. This line could be caused by thruster noise. If the radial line appears with the Sonar Head out of water, it could indicate noise in the power line or a fault in the Sonar Head. |
|
C |
Make sure that the bottom appears across the entire width of the sonar view. If the edges appear weak, and profile points are not detected at the edges, make sure there are no obstructions preventing
the Sonar Head’s receive. (i.e. improperly installed guard ring or proximity to the vessel hull/keel). |
