P4.0: Resetting to factory default settings (pH)

calibration data and any other pH setup functions you might have changed.
The following settings will remain as you have set them:

•
The temperature offset calibration value
•
All DO calibration data and parameters
There are also some other parameters that retain settings when reset is done. See Addendum
