  • Page 30: Configuring The Noise Floor

    Speed Sensors | V5 | Sensor Configuration Configuring the Noise Floor Even when the sensor is in a silent environment, a small level of noise is detected. You need to measure this level of noise so that the sensor ignores it when operating, otherwise it could have effects on the echogram.

  • Page 31: Calibrating The Sensor For Target Strength Value

    Speed Sensors | V5 | Sensor Configuration 5. Click Apply and make sure there is a green check mark Calibrating the Sensor for Target Strength Value For V3 version of the sensor, you need to calibrate the sensor to offset the variability of the sensor transducer and of sound transmission.
  • Page 32 Speed Sensors | V5 | Sensor Configuration 2. Before putting the sensor in water: a) Activate and deactivate the water-switch to connect the sensor to Mosa2 via a wireless signal. b) Cover the water switch and charging pins with adhesive tape to prevent water from touching them.
  • Page 33 Speed Sensors | V5 | Sensor Configuration Note: If the sensor is not correctly placed, you may have an error message asking you to correct the pitch and/or roll angle. The sensor sends a series of 5 pings to calculate if the echo is consistent and constant. A new target strength offset is calculated.

  • Page 40: Checking Speed Measures With Em Log Tester

    • The sensor is connected to Mosa2. About this task If you do not have the EM Log tester, please refer to your local Marport sales office. The EM Log tester is also useful to check that the sensor is still operational over time. You can check speed before every fishing campaign to make sure the sensor works properly.
  • Page 41 Speed Sensors | V5 | Sensor Configuration Troubleshooting: If the along speed is negative and the across speed positive, it means that you placed the EM Log tester upside down or that the cabling inside the sensor is inverted. Troubleshooting: If an error message says the offset and gain are incorrect or the EM log tester is broken, it may be because the EM log tester was not totally immobile during the test.

  • Page 42: Configuring The Uplink Power

    Speed Sensors | V5 | Sensor Configuration Configuring the Uplink Power You can increase the uplink power of the sensor to increase the power of the signal transmitted.
