Blank value correction (Bw Corr)

If the ion concentration in the sample is so small that it does
not lie in the linear range of the electrode, you can increase
the ion concentration in the linear range with the blank value
correction by the addition of a blank value solution.
The displayed measured value is the difference between the
actual measured value and the determined blank value.
