1. Fill a clean 10 mm cell with
water sample
.
2. Place the cell in the sample chamber making sure that
the positioning is correct.
3. Press
ZERO
key.
4. Remove the cell from the sample chamber. Empty the
cell and dry completely.
5. Rinse a beaker with the water sample and
empty it,
leaving a few drops remaining in the beaker
.
6. Add
one DPD No. 1 tablet
straight from the foil and
crush the tablet using a clean stirring rod.
7. Add
10 ml of water sample
and dissolve the tablet.
8. Fill the 10 mm cell with the colored test solution.
9. Place the cell in the sample chamber making sure that
the positioning is correct.
10. Press
TEST
key.
11. Remove the cell from the sample chamber and return
the colored test solution completely back into the bea-
ker.
12. Add
one DPD No. 3 tablet
straight from the foil to the
same water sample and crush the tablet using a clean
stirring rod. Dissolve the tablet.
13. Fill the 10 mm cell with the colored test solution.
14. Place the cell in the sample chamber making sure that
the positioning is correct.
15. Press
TEST
key.
Wait for a
reaction period of 2 minutes
.
After the reaction period is finished the measurement
starts automatically.
The result is shown in the display in:
