SVProf – Sound velocity profile acquisition. 5. Instruction for use. This chapter describes briefly how to perfom common tasks in SVProf. 5.1 Importing profile(s) online from a svep. This explains how to import up to four profiles from a sound velocity profiler. The profiler must be compatible with the SVEP 5002 from GMI systems. 1. Confirm via ‘Options – Select COM port’, that the port you have selected is the COM port the SVEP is connected to. Also note that the baud rate, parity, databit and stop bit is set correctly. Typically 9600,N,8,1 2. Select ‘File – Import – Online from SVEP’. The following dialog appears.

3. Select the profiles that you wish to download and click the ‘Download’ button. When the process is done, the ‘OK’ button is enabled. Click it to continue. The following dialog appears. 4. Enter the ship identifier and press ‘OK’. The identifier will be used when generating the name of the profile documents.

5. A document for each downloaded profile is opened. 5.2 Importing a NaviScan profile. This procedure will import a file in NaviScan format and convert it into a *.sva document. The only data available in the NaviScan file is the sound velocity profile. All remainding fields will be set to zero (0.00).

SVProf – Sound velocity profile acquisition. 1. Select ‘File – Import – NaviScan SVEP’. 2. Browse to the location of the file and select it. Typically the file has the extension *.txt. 3. If the conversion is succesful a new document is opened. The *.txt extension, if any, is replaced with *.sva.

SVProf – Sound velocity profile acquisition. 5.3 Exporting a profile for use in NaviScan. This procedure describes how to export a sound velocity profile to NaviScan for online use. 1. Open or import a profile document. 2. Select the sound velocity profile to export and select ‘File – Export – NaviScan SVEP’. 3. The default folder is C:\temp, which is where NaviScan looks for a sound velocity profile. Keep the proposed file name (Specsvp.txt) and choose ‘Save’. 4. At this point NaviScan can not tell that the profile has changed. Therefore in NaviScan select the following menu option: ’Options – Load/Reload SVel profile’. This will make NaviScan use the updated profile.

SVProf – Sound velocity profile acquisition. 5.4 Editing a loaded profile. This procedure describes how to edit a loaded profile document. 1. Open or import a profile. 2. Select ‘Edit – Profile data’ from the menu or ‘Edit profile data’ from the context sensitive menu. 3. The profile is opened in notepad. Now you can add new rows at the bottom or modify existing rows. You can also modify the header information, but be sure only to modify the information outlined in the picture below. Any information entered in the outlined areas will be saved. The bottom depth, Mean SVEL and Mean density are calculated from the profile data. So entering any values here will have no effect. If you add or modify a row of data, be sure to enter values in all columns. Else SVProf will fail to reload the file and revert all changes made.
