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 tipically deviates slightly from the ideal values.
If the actual isopotential pH for an electrode is known, it can be set by accessing this option. The isopotential pH
limits (low and high) will be displayed on the LCD.
Note: If the isopotential point has been modified, recalibration
must be performed for the respective channel.
