Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local,
regional and national regulations.
The generic steps to do a test follow.
To do a test for a specific parameter (e.g., chlorine), download the test procedure from
the manufacturer's website. Refer to Download a test procedure on page 11.
1. Push to select the applicable measurement range (e.g., LR or HR).
2. Prepare the blank. Refer to the test procedure.
3. Clean the sample cell with a no-lint cloth.
4. Insert the blank sample cell into the cell holder. Make sure to install the blank sample
cell in the correct and consistent orientation so that the results are more repeatable
and precise. Refer to Figure 5.
5. Install the instrument cap over the cell holder. Refer to Figure 6.
6. Push to set the instrument zero.
7. Remove the blank sample cell.
8. Prepare the sample. Refer to the test procedure.
9. Clean the sample cell with a no-lint cloth.
10. Insert the sample cell into the cell holder. Make sure to install the sample cell in the
correct and consistent orientation so that the results are more repeatable and precise.
Refer to Figure 5.
11. Install the instrument cap over the cell holder. Refer to Figure 6.
12. Push . The display shows the results in concentration units or absorbance.
Note: The result flashes if the result is less or more than the instrument range.
13. Remove the sample cell from the cell holder.
14. Immediately empty and rinse the sample cell. Rinse the sample cell and cap three
times with deionized water (or distilled water).
Note: As an alternative, use tap water to rinse the sample cell if the samples measured have a
higher concentration than the tap water.
