7.3.3 Sample addition
In the "Sample addition" procedure, a known amount of sample is added to the
standard solution.
The ion concentration in the sample is calculated from the change in potential.
Calibration
Measuring
1. Select the measuring method (see section 7.3 S ELECTING THE MEASU -
RING METHOD , page 56).
2. Prepare two standard calibration solutions.
3. Perform a two-point calibration according to user guidance.
4. The calibration record is displayed as soon as a stable value is
achieved for the second standard calibration solution.
