Isopotential Point
This option allows the user to edit the isopotential point of the electrode used for pH measurements.
The isopotential point is the mV reading for an electrode at which temperature has no effect on the
measurement. The ideal electrode has an isopotential point of 0.0 mV and 7.00 pH, while an actual
electrode typically deviates slightly from the ideal values.
If the actual isopotential pH for an electrode is known, it can be set by accessing this option.
Note: If the isopotential point has been modified, recalibration must be performed.
To set the Isopotential Point:
