9.7 Viewing pH Electrode Data – P5.0
In pH mode, Program 5 has three “view only” options that lets you check the
electrode parameters for diagnostic purposes.
P5.1: view pH electrode offset
P5.2: view pH electrode slope
P5.3: view temperature probe offset (ATC on only)
These parameters will change each time you recalibrate the controller.
