Not to be short, but if you want help in a hurry (and it seems you do), I highly recommend calling the manufacturer. I have a Compupool, and I've had good luck talking with their technical support. Even though I have experience running a salt pool, I do not have experience with your system. The folks who make your system are the experts.
My specific unit was not properly calibrated when I got it. Compupool was able to send me documentation on how to recalibrate it. It now reads exactly the same as my tests.
