Apex salinity probe question

[morganatlanta]

So if I have temperature compensation set to 2.2 on my Apex salinity/conductivity probe, why does my graph of salinity look like this?

Do you happen to have a Temp probe hooked up to the PM2?

Edit :Never mind, I see that you do have the cond6 and temp6 installed.

Check out this thread on neptune's forum.

I upped the temperature compensation setting 0.1 per day until I got a stable salinity today with it at 2.7. I'm a little surprised that it would need to be so much higher than the 2.2-2.3 value they quote. You would think it would be a fundamental property rather than something that would vary so much from one setup to another.
