Replacing The Pull Cords - Marport CATCH User Manual

Not used for more than 3 months
Every 2 years
If the sensor has not been not used for more than 3 months, we highly recommend to
check the following points before using it:
• Make sure the sensors on the end cap are in good condition and clean.
• Connect the sensor to a charger and check the charging status.
• Switch on the sensor by shorting the center lug to the negative lug, then listen for
a ping noise and check if you see the LED switched on.
• Test the sensor measures with Mosa2: depth, temperature, pitch, roll, and if
applicable: spread distance, echogram, catch status, speed measures (using the
EM log tester).
• If you have a test hydrophone, check the reception in the wheelhouse with Scala.
You can replace the catch pull cords when they are worn out or damaged.
For this task you need the following tools:
