PROCEDURE<br />
Use 10 mm square cell adapter.<br />
1. Press and hold ON button until colorimeter turns on.<br />
2. Press ENTER to start.<br />
3. Press ENTER to select Testing Menu.<br />
4. Select ALL <strong>TEST</strong>S (or another sequence containing 18 Cl<br />
Total-UDV)from <strong>TEST</strong>ING MENU.<br />
5. Scroll to and select 18 Cl Total-UDV from menu.<br />
6. Rinse a clean vial (0156) with sample water.<br />
7. Use the syringe (1184) to add 3mL of sample to the vial.<br />
8. Insert the vial into chamber, close the lid and select SCAN BLANK.<br />
9. Remove the vial from the colorimeter.<br />
10. Use the syringe (1184) to add 3mL of sample to a *Total Chlorine UDV<br />
vial (4312).<br />
11. Shake vigorously until powder dissolves completely.<br />
NOTE: If powder residue remains in the bottom of the vial after inverting<br />
or air bubbles form, invert once more and tap bottom of vial sharply once<br />
or twice to dislodge powder and bubbles. Mix.<br />
12. Wait 2 minutes.<br />
13. Insert tube into chamber, close lid and select SCAN SAMPLE. Record<br />
result in ppm total chlorine.<br />
14. Press OFF button to turn the colorimeter off or press EXIT button to exit<br />
to a previous menu or make another menu selection.<br />
NOTES: For best possible results, a reagent blank should be determined<br />
to account for any contribution to the test result by the reagent system.<br />
To determine the reagent blank, follow the above test procedure to scan<br />
a distilled or deionized water blank. Then follow the above procedure to<br />
perform the test on a distilled or deionized water sample. This test result<br />
is the reagent blank. Subtract the reagent blank from all subsequent test<br />
results of unknown samples. It is necessary to determine the reagent<br />
blank only when a new lot number of reagents are obtained.<br />
UDVs from opened pouches should be used promptly. Store unused vials from<br />
opened pouches in the Foil Storage Bag (9467) to extend the shelf life of the<br />
reagent. Generally, UDVs stored in the bag should be used within 10 days if<br />
the humidity is less than 50% and within 5 days if humidity is greater than<br />
50%. The Foil Storage Bag contains a desiccant pack with indicator. When<br />
the indicator in the window turns from blue to pink, the bag should be<br />
replaced.<br />
