    Temp probe reading 20.9

    So I had to move my apex fusion which meant disconnecting all of my probes. Now my temp probe reads 20.9 and my conductivity probe reads 54.3. Do they just need time to adjust? I tried re-calibrating my cond prob and couldn’t get it to calibrate correctly either. Any suggestions?

    A reading like that for the temp probe means it's disconnected. Try reseating and if it still won't read you might need a new one.

    The cond is probably just reacting to the really low temp value and might restore normal readings when you have that in check.

    You might be an engineer if...You have no life and can prove it mathematically.

    You were right. Wasn’t plugged in quite all the way. However, my salinity is still reading high (always has). I have followed all of the post for calibrating and if I use the basic mode it never checks within range when in the solution. I’m not exactly sure how to follow advanced mode either. Still a newbie here.

    Unplug the cond probe and run a manual calibration and just hit next through until it finishes (this will "reset" it). Then plug it back in and run through another manual calibration with the solution making sure to match the packet temp to tank temp for 30 min and when you do the dry step just rinse in RODI and pat dry with a paper towel.
