6. Thoroughly rinse the turbidity sensor with distilled water and dry it with
a lint-free cloth.
7. Immerse the turbidity sensor in the test sample at an angle.
8. Position the turbidity sensor in the measuring vessel.
9. Use <> <> and <><> to set the concentration of the standard
solution for each digit and confirm with <ENTER>.
The standard solution is measured.
The measured value is checked for stability (AutoRead).
10. Wait for the end of the AutoRead measurement.
The calibration display for the next standard solution appears.
