Follow these steps to prepare your HI2020 meter for first use and ensure proper functionality.

1. അൺപാക്ക് ചെയ്യുന്നു: പാക്കേജിംഗിൽ നിന്ന് എല്ലാ ഘടകങ്ങളും ശ്രദ്ധാപൂർവ്വം നീക്കം ചെയ്യുക. ഭാവിയിലെ സംഭരണത്തിനോ ഗതാഗതത്തിനോ വേണ്ടി പാക്കേജിംഗ് സൂക്ഷിക്കുക.
2. പവർ കണക്ഷൻ: Connect the provided power adapter to the meter's USB port and a standard power outlet. The meter can also operate on its internal rechargeable battery. Ensure the battery is sufficiently charged for portable use.
3. ഇലക്ട്രോഡ് കണക്ഷൻ: Connect the pH electrode and, if separate, the temperature probe to their respective ports on the top of the meter. Ensure connections are secure and fully inserted.
4. പ്രാരംഭ പവർ ഓൺ: Press the power button (usually located on the front or side) to turn on the meter. The display should illuminate and show initial readings or a welcome screen.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ

Basic pH Measurement

1. Electrode Preparation: Ensure the pH electrode is clean and properly conditioned. Remove the protective storage cap and rinse the electrode bulb and junction with distilled or deionized water.
2. Sampനിമജ്ജനം: Submerge the electrode tip and temperature probe into the sample solution. Ensure the liquid level covers the sensing bulb and the reference junction of the electrode.
3. Reading Stability: Gently stir the solution to ensure homogeneity. Allow the reading on the display to stabilize. The meter will typically indicate stability with an icon or message.
4. റെക്കോർഡിംഗ്: Once the reading is stable, record the pH and temperature values displayed.
5. Post-Measurement: Rinse the electrode thoroughly with distilled water and replace the storage cap with fresh storage solution.

ബട്ടൺ പ്രവർത്തനങ്ങൾ

• CAL / MODIFY: Initiates the calibration process; used to modify settings within menus.
• റേഞ്ച്: Toggles between different measurement ranges or parameters (if applicable).
• UP / DOWN Arrows: Navigates through menu options and adjusts numerical values.
• ലോഗ്: Records the current stable measurement data into the meter's memory.
• GLP / CFM: Accesses Good Laboratory Practice (GLP) data, including calibration history; used to confirm selections.
• SETUP / CLR: Enters the meter's setup menu for configuration; used to clear logged data or settings.
• ആർസിഎൽ: Recalls previously logged measurement data from the meter's memory.

കാലിബ്രേഷൻ

Regular calibration is essential for maintaining the accuracy of your pH meter. It is recommended to calibrate the meter at least once a day, or when using a new electrode, after cleaning the electrode, or if high accuracy is required.

1. തയ്യാറാക്കൽ: Have your pH 4.01, 7.01, and 10.01 buffer solutions ready. Ensure they are fresh and at room temperature. Use separate beakers for each buffer to avoid contamination.
2. കാലിബ്രേഷൻ ആരംഭിക്കുക: Turn on the meter. Rinse the electrode with distilled water. Press the CAL button. The meter will prompt you for the first buffer solution, typically pH 7.01.
3. ആദ്യ ബഫർ (പിഎച്ച് 7.01): Immerse the electrode tip and temperature probe into the pH 7.01 buffer solution. Gently stir and wait for the reading to stabilize. The meter will automatically recognize the buffer and confirm calibration for this point.
4. രണ്ടാമത്തെ ബഫർ (pH 4.01 അല്ലെങ്കിൽ 10.01): Rinse the electrode thoroughly with distilled water. Immerse it into the next buffer solution (e.g., pH 4.01 for acidic range measurements or pH 10.01 for alkaline range measurements). Wait for stabilization and confirmation.
5. മൂന്നാമത്തെ ബഫർ (ഓപ്ഷണൽ): For a three-point calibration, rinse the electrode again and immerse it in the remaining buffer solution. Wait for stabilization and confirmation.
6. Save Calibration: Follow the on-screen prompts to save the calibration data. The meter will display a message indicating successful calibration.

Image: Three bottles of pH buffer solutions, typically pH 4.00, pH 7.00, and pH 10.00, which are crucial for accurate calibration of the pH meter. These solutions ensure the meter provides precise readings across the pH scale.

ഇലക്ട്രോഡ് കെയർ

• സംഭരണം: Always store the pH electrode in its protective cap filled with Hanna storage solution or pH 7.01 buffer. Never store the electrode dry, as this will dehydrate the sensing bulb and lead to sluggish response and inaccurate readings.
• വൃത്തിയാക്കൽ: If readings become sluggish, erratic, or inaccurate despite calibration, the electrode may need cleaning. Use a specialized electrode cleaning solution recommended by Hanna. Follow the cleaning solution's instructions carefully.
• കഴുകൽ: Rinse the electrode thoroughly with distilled or deionized water before and after each measurement to prevent cross-contamination and buildup.

മീറ്റർ കെയർ

• വൃത്തിയാക്കൽ: Wipe the meter body with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casinജി അല്ലെങ്കിൽ ഡിസ്പ്ലേ.
• സംഭരണം: Store the meter in a cool, dry place away from direct sunlight, extreme temperatures, and corrosive environments when not in use.
• ബാറ്ററി: For prolonged storage, ensure the internal battery is partially charged (around 50%) to maintain battery health.
