Measuring
7. Start the measurement with <F1> continue.
An entry window appears.
8. Prepare the standard solution.
9. If necessary, add the ISA/TISAB solution to the standard solution.
10. Thoroughly rinse the electrode with deionized water.
11. Immerse the electrode in the standard solution (complexing agent or
precipitating agent).
12. Using <><> and <ENTER>, enter the values for the volume of the
standard solution (Std. volume), the concentration of the standard solu-
tion (Std. conc.) and the volume of the ISA/TISAB solution (ISA/TISAB
vol.).
13. Select continue with <><> and start the measurement with
<ENTER>.
When the measurement is finished an entry window appears.
14. Add the sample to the standard (complexing agent or precipitating
agent).
15. Using <><> and <ENTER>, enter the value for the volume of the
sample (Sample volume).
16. Select continue with <><> and start the measurement with
<ENTER>.
The measurement result is displayed when the measurement is com-
pleted.
