At-Sea Test - Klein 5000 SERIES Operation And Maintenance Manual

Quick Start Installation and Operating Guide
5. On the computer, start SonarPro and observe that the towfish is transmitting by
viewing the output pulse in the Scan window. Also check that GPS data are being
displayed in the Information window in SonarPro.
6. Select the 150-meter range and perform a rub test on the port and starboard
transducers to confirm that the receiver mode is operating properly. Vigorously
rub each transducer, one at a time, while observing the Sonar Viewer window in
SonarPro for returns.
7. Exit SonarPro and turn off the computer and the TPU.
This completes the deck test.

At-Sea Test

To perform the at-sea test:
1. With the computer running and at the Windows desktop, turn on the TPU.
After the TPU boots (as in Step 3 above), start SonarPro. Again, check for the
output pulse, and then carefully deploy the towfish.
2. Adjust the towfish within the water column so that it is at a comfortable altitude
off the bottom and under the boat wake (about 15 percent of range). A good
starting vessel speed is around 4 or 5 knots. Check for the following:
• The image is satisfactory.
• Pitch, roll, depth, and altitude are being displayed.
• Speed and heading are being displayed from the GPS.
3. Make a series of runs on the same navigation line at selected range settings of
75 meters and then 100 meters, at speeds from 4 to 10 knots in increments of
2 knots. Record and view the side scan sonar data.
4. Observe the data for repeatability and full along-track coverage as a function of
speed and range settings.
This completes the at-sea test.
