3. Пачатковая налада
Before using your HI784 Marine Ammonia Checker, ensure it is properly set up.
3.1 Устаноўка батарэі
The device requires 1 AAA battery, which is included. To install or replace the battery:
- Знайдзіце вечка батарэйнага адсека на задняй панэлі прылады.
- Зніміце вечка.
- Insert one AAA battery, observing the correct polarity (+/-).
- Надзейна заменіце крышку батарэйнага адсека.
3.2 Падрыхтоўка да вымярэння
Ensure you have all necessary reagents and clean cuvettes ready before beginning the measurement process.
4. Інструкцыя па эксплуатацыі
Follow these steps carefully to ensure accurate ammonia measurements.
4.1 Працэдура вымярэння
- SampПадрыхтоўка: Пераканайцеся, што вада sample does not contain any debris. Prepare the sample cuvette immediately after collecting the sampле з танка.
- Даданне рэагента: Hold dropper bottles completely vertically and squeeze slowly to ensure correct drop size when adding reagents.
- 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.
- 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.
- Час: Не дазваляйце рэагаваць сample stand too long after reagent has been added, as accuracy will be affected. The built-in timer will guide you through reaction times.
- Чытанне: Follow the specific instructions provided with your reagent kit for the exact steps to take a reading.
- Утылізацыя: Адмоўцеся ад 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. Тэхнічнае абслугоўванне
5.1 Ачыстка
- Regularly clean the outside of the checker with a soft, damp тканіна.
- 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.
- Не выкарыстоўвайце абразіўныя ачышчальнікі або растваральнікі.
5.2 Захоўванне
Store the HI784 checker in a cool, dry place away from direct sunlight and extreme temperatures. Keep reagents properly sealed and stored according to their specific instructions.
6. Выпраўленне непаладак
If you encounter issues with your HI784 checker, consider the following common solutions:
- Няправільныя паказанні:
- Ensure cuvettes are clean, dry, and free of scratches or fingerprints.
- Verify correct reagent addition and reaction times.
- Check for air bubbles in the sample after reagent addition; gently tap to remove.
- Пераканайцеся, што сample does not contain debris.
- Праблемы з адлюстраваннем:
- Праверце ўзровень батарэі і пры неабходнасці заменіце яе.
- Ensure the battery is installed with correct polarity.
- Прылада не адказвае:
- Заменіце батарэю.
- Пераканайцеся, што батарэйны адсек надзейна зачынены.
If problems persist, contact Hanna Instruments customer support for further assistance.
