1 Note if in doubt click the “Help” button HiPAP CalibrationNote if in doubt click the “Help” button
2 Velocity CastIt is important to have the correct Sound Velocity for the correct use of the HiPAP and HPR.Do a velocity cast, process the cast into a comma separated file, with Depth, and Speed of Sound.
5 Entering the Velocity Profile A picture similar to the slide below will appear.
6 Select “File”, and “Open, or click the “Icon” to open a file. The file open Icon
7 A dialog box similar to this will open A dialog box similar to this will open. Either steer to the place where your “new” velocity cast is situated, or copy your file into the APOS\Data folder and select it
8 Your velocity cast should open in a text format Your velocity cast should open in a text format. You can edit the file like the example, giving a date or location to make the file meaningful.Added date information
11 You can now give a Heading text to your Profile, and select the fist line to convert. Use the depth neares to just below the transducer. Also make sure you know which is the depth and velocity column in your file.
15 And Finally Close down all the open boxes. Save everything when prompted.When finished click the Sound Velocity icon again.Make sure you have saved the correct Active Velocity.Close the Velocity Profile Window.
16 Add the Transponder as usual Enter the Correct serial numberDon’t forget the release boxSelect MPT
17 Go to Configure Transponder Either from the menu on the top, Configure Transponder, or right click the icon and select Transponder
18 Tab to the second PageThe Release button is down here. You only get asked once if you are sure you want to Release the TransponderThe second page is marked as Transponder FunctionsIt is quite useful to configure the Green Dot screen as Trend. Then setup the Trend menu to monitor Depth from the Transponder
19 Activate the Calibration transponder, after it has been deployed and is on the bottom
23 Select your Transponder A dialog ox like this will appear. Select your calibration transponder from the drop down menu.Also if you have more than one HiPAP, select the one you are calibrating.Drop down MenuThe transducer being calibrated
24 Note. You must have GPS, preferably DGPS into the system and working. The TransponderThe Transducer
27 Decide if you want to start and stop the calibration manually or automatically after a chosen number of position pairs .Normally I would select “After # position pairs” choose 100
28 The Pattern It doesn’t matter on the chosen pattern The preferred method is 4 Cardinal points and a spin stopping at each quadrant, over the top of the transponder.Note Stay in the beam footprint of the transponderIe a 324 transponder, is a 30Khz, 2000 meter depth rated, and a +/- 45 degree beam pattern.
43 When you get to this one Right click on the transponder. Select “Save Measurements As”Save the file, the default is the Transponder channel, ie B42The transducer being calibrated ie 11,21, 31 etc if you have more than one,And the time the file was saved.You can name the file anything you like.Save Measurements as
