PH PinPoint Calibration

Question for the PH PinPoint Owners.

I am Calibrating the PH Controller with a 4.0 and a 7.0. When I finish, I check it with a 10.01. I must not be doing it right or my probe is going bad. It shows my PH is now 7.8 and when I use aAquarium Systems Ph Tester it says I am at 8.0 Is that .2 a big deal. Also when calibrating how many times do you go back and forth with the Calib and the Slope adjustment? It seems that I am going back and forth..

Thanks for any help

I think Melev just answered a post like this stating to try calibrating w/ 7 and 10. My milwaukee calibrates at 4 and 7 and I have a .2 difference too, so i'm going to try this. I keep replacing probes because of this problem but hopefully it's just calibrating so low...
