4.7.4 Checking the Sensors
Sensor readings can be read out directly in the Information window in SonarPro.
Move the towfish in pitch, roll and heading and check to see if the readings
change. If you have no sensor readings, check that the cable is properly plugged
into the sensor interface board at JP5. Also check that the cable is properly
connected at the compass board.
4.7.5 Calibrating the Optional Temperature Probe
The optional temperature probe adjustment is made on the Sensor Interface board.
With the towfish open, turn the towfish on, and let the system boot up. Start
SonarPro. With the towfish at ambient temperature, measure the ambient
temperature with an accurate thermometer. Set the potentiometer on the Sensor
Interface board, which is shown in Figure 4-15, to the current temperature. The
temperature can be viewed in the Information window in SonarPro.
4.7.6 Calibrating the Compass
The compass is calibrated using the Compass Calibration Wizard in SonarPro. To
start the wizard, click
Run Compass Calibration Wizard
on the Towfish
Diagnostics tab of the Sonar Interface dialog box. Follow the instructions and play
the demonstration animation.
The compass calibration must be performed away from all magnetic and metal
sources, most likely off the ship. You enable the towfish compass calibration mode
and then rotate the towfish slowly 360 degrees in a circle (more than a minute). At
the same time you must pitch and roll the towfish beyond its 20 degree limits, we
suggest 45 degrees to be safe.
