P3 - Ex upgrade issues with Cond

[turaki tim]

Hi team!
I just upgraded my P3 to eX.
After the upgrade I also uploaded FW 5.07

However, type is still Profilux 3 and the Cond probe reads 0mS.

Any thoughts please?

Did you run the command "hardware-upgrade eXtended" from the "Extra's" menu in the Profilux Control Software.

I found the command and all is working now.

HOWEVER - the Cond reading on the P3 is equivalent to a salinity (PTU) of 26, or less than 30mS!!! On my dd20 ATC refractometer, it reads 34ppt. One is obviously very wrong and I must admit that I have been struggling with STN on a lot of my SPS recently. Have I been trying to keep my reef at a very low salinity recently, which would explain de deterioration?

Any thoughts?

Try recalibrating the Probe, but make sure you float your Calibration fluids in your tank/sump for a while so the temperatures match, seemed to help me get a more accurate reading
