I am having a problem calibrating my Ph probe for my APEX. I am using the 7 and 10 solution and everything work fine until I get to the 10 solution and then it times out every time. I have tried it 3 times. Any help would be appreciated.

Did you make sure to twist the connector on?

Try a manual calibration if you are doing automatic now. Let it sit for 5 minutes in each solution. Do a second manual calibration and let it sit for 10 minutes in each.
