4.5.7 Measuring diluted samples

If the concentration of a sample exceeds the measuring range of a method,
you can specifically dilute the sample so that the concentration of the diluted
sample is in the measuring range of the method. Thus a valid measurement
is possible.
After entering the factor for the dilution the meter converts the concentration
to that of the undiluted sample.
Note
Optimum measurement results are achieved if the concentration of the
diluted sample is in the middle of the measuring range of the method after
diluting.
