9. Immerse the electrode in the sample.
10. Using <> <> and <ENTER>, select the values for the volume of the
sample (Sample volume) and the volume of the ISA/TISAB solution
(ISA/TISAB vol.).
11. Select Continue with <> <> and start the measurement with
<ENTER>.
When the measurement is finished an entry window appears.

12. Add the standard (complexing agent or precipitating agent) to the sam-
ple.
13. Using <> <> and <ENTER>, enter the values for the volume of the
standard solution (Std. volume) and concentration of the standard solu-
tion (Std. conc.) .
14. Using <> <> and <ENTER>, set the ion type for the ion in the stan-
dard (Ion type) if necessary.
On selection of the ion type that can be defined (ION):
Using <> <> and <ENTER>, set the valence (Valency) and molar
weight (Molar mass) for the ion in the standard solution.
15. Select Continue with <> <> and start the measurement with
<ENTER>.
The measurement result is displayed when the measurement is com-
pleted.
