4. Konfiguracja i kalibracja

For accurate readings, the pH meter must be calibrated before first use and regularly thereafter. The kit includes 4.00 pH and 7.00 pH calibration solutions.

4.1 Wstępne przygotowanie

1. Zdejmij nasadkę ochronną z elektrody.
2. Przepłucz elektrodę wodą destylowaną lub dejonizowaną.
3. Gently blot dry with a clean tissue. Do not rub.

4.2 Proces kalibracji

1. Turn on the pH meter.
2. Immerse the electrode into the 7.00 pH calibration solution. Ensure the electrode is fully submerged.
3. Press and hold the CAL button until the display shows 'CAL' or begins flashing. The meter will automatically recognize the solution and calibrate. Wait for the reading to stabilize.
4. Opłucz elektrodę wodą destylowaną i osusz.
5. Immerse the electrode into the 4.00 pH calibration solution.
6. Press and hold the CAL button again. The meter will calibrate to the 4.00 pH solution. Wait for the reading to stabilize.
7. Opłucz elektrodę wodą destylowaną i osusz.
8. Your meter is now calibrated and ready for use.

Notatka: Regular calibration (e.g., every few weeks or before critical measurements) is crucial for maintaining accuracy, especially with frequent use or after long periods of storage.

5. Działanie

5.1 Wykonywanie pomiaru

1. Ensure the meter is calibrated as described in Section 4.
2. Remove the protective cap and rinse the electrode with distilled water.
3. Zanurz elektrodę w sample solution you wish to test. Ensure the electrode is fully submerged.
4. Gently stir the meter in the solution to remove any air bubbles.
5. Wait for the reading on the display to stabilize. This typically takes a few seconds. The display will show both pH and temperature.
6. Record your measurement.
7. After use, rinse the electrode thoroughly with distilled water.

6. Konserwacja i przechowywanie

Proper maintenance and storage are crucial for extending the lifespan and accuracy of your pH meter.

6.1 Czyszczenie elektrody

• Przed i po każdym użyciu należy zawsze przepłukać elektrodę wodą destylowaną lub dejonizowaną.
• If the electrode becomes dirty or contaminated, gently clean it with a soft brush or cotton swab and a mild cleaning solution (e.g., diluted detergent or specialized electrode cleaning solution). Rinse thoroughly afterward.
• Avoid touching the glass membrane directly, as oils from your skin can affect its performance.

6.2 Przechowywanie

• The pH electrode should always be stored in a storage solution or 4.00 pH calibration solution. Never store it dry or in distilled water, as this can damage the glass membrane.
• Ensure the protective cap is securely placed over the electrode when not in use to prevent drying out and physical damage.
• Przechowuj miernik w chłodnym i suchym miejscu, z dala od bezpośredniego światła słonecznego i ekstremalnych temperatur.

7. Rozwiązywanie Problemów

• Niedokładne lub niestabilne odczyty:
  • Ensure the meter is properly calibrated. Re-calibrate if necessary.
  • Check if the electrode is clean and free from debris. Clean as per Section 6.1.
  • Verify that the electrode is fully submerged in the solution.
  • Upewnij się, żeamptemperatura mieści się w zakresie roboczym miernika.
• Licznik się nie włącza:
  • Sprawdź poziom naładowania baterii. Wymień baterie, jeśli są niskie.
  • Ensure the battery compartment is properly sealed.
• Długi czas reakcji:
  • The electrode may be dry or contaminated. Re-hydrate by soaking in storage solution for a few hours, then re-calibrate.
  • The electrode may be nearing the end of its lifespan.
• Błąd kalibracji:
  • Ensure you are using fresh, unexpired calibration solutions.
  • Verify the electrode is clean and properly submerged.
  • If issues persist, the electrode may be damaged or worn out.
