Data in Scala2 is wrong
Data displayed in Scala2 is wrong. For sensors with echograms, the echogram is noisy.

- First, check that the sensor frequencies and telegrams are the same in the sensor configuration (via Mosa2) and the receiver configuration (via Scala2 or the system web page).
- Check the frequencies of your other sensors and make sure there is enough distance between them.
- Check the noise on the spectrum (see Checking Noise Interference). If the
frequency where the sensor is placed is too noisy, change for a less noisy frequency:
- Seine sensors with depth and options: see Configuring Seine Sensor Telegrams
- Seine Explorer: see Configuring the Uplink, Up (Side) and Down Settings
Important: Do not forget to also change the frequency on the system web page (accessible through Scala2 receiver page). - You can increase the uplink power of the sensor to increase the power of the signal transmitted to the receiver: see Configuring the Uplink Power.
- For sensors with
echograms you can change the Echogram filter on the system web page (Scala2 receiver page):
- From Scala2, click and enter the password copernic.
- Right-click the IP address of the receiver at the bottom of the page, then click Configure Receiver.
- From the left side of the page, click the name of the sensor.
- From the sensor configuration page, click Configure next to Filter.
- From NBTE Echograms Filter select Echosounder and Interference Reduction Medium or High.
