4. Instrukcja obsługi

Follow these steps carefully to ensure accurate ammonia measurements.

4.1 Procedura pomiarowa

1. Sample Przygotowanie: Upewnij się, że wodaample does not contain any debris. Prepare the sample cuvette immediately after collecting the sample ze zbiornika.
2. Reagent Addition: Hold dropper bottles completely vertically and squeeze slowly to ensure correct drop size when adding reagents.
3. Cuvette Handling: Whenever the cuvette is placed into the checker, it must be dry on the outside and free of fingerprints, oil, and dirt. Wipe the cuvette thoroughly with a microfiber cleaning cloth prior to insertion.
4. Avoid Bubbles: Shaking the cuvette can generate bubbles, which may cause higher readings. To obtain accurate measurements, remove such bubbles by swirling or gently tapping the cuvette.
5. Chronometraż: Nie pozwól zareagować sample stand too long after reagent has been added, as accuracy will be affected. The built-in timer will guide you through reaction times.
6. Czytanie: Follow the specific instructions provided with your reagent kit for the exact steps to take a reading.
7. Sprzedaż: Odrzuć sample immediately after the reading has been taken to prevent permanent staining of the glass cuvette.

Always refer to the specific instructions on the reagent packaging or in the full user manual for additional directions and precautions.

5. Konserwacja

5.1 Czyszczenie

• Regularly clean the outside of the checker with a soft, damp płótno.
• Ensure the cuvette is always clean and free of scratches, dirt, or fingerprints, as these can interfere with light path and affect readings. Use a microfiber cloth for cleaning cuvettes.
• Nie należy używać środków czyszczących o właściwościach ściernych ani rozpuszczalników.
