If dry is reading that high then you need to reset the port. Not necessary but you can un-plug the probe; then re-run through the manual calibration pausing 1-3 seconds between steps then at then end of the calibration reboot the Apex, (re-plug in the probe if you disconnected it) and then re-calibrate the probe using the manual method and your dry numbers can be 60-80ish range and then in the solution it should be 300-800. After calibration the probe should read 34.7-35.3. If it does you have calibrated the probe correctly.
