4.1 ബാറ്ററി ഇൻസ്റ്റാളേഷൻ

1. Ensure the meter is off.
2. ബാറ്ററി കമ്പാർട്ട്മെന്റ് കണ്ടെത്തുക.
3. Insert four 3V CR-2032 Lithium Metal batteries, observing correct polarity.
4. ബാറ്ററി കമ്പാർട്ട്മെൻ്റ് സുരക്ഷിതമായി അടയ്ക്കുക.

4.2 Electrode Preparation

1. ഇലക്ട്രോഡിൽ നിന്ന് സംരക്ഷണ തൊപ്പി നീക്കം ചെയ്യുക.
2. Rinse the electrode tip with distilled water.
3. If the electrode appears dry, soak it in electrode storage solution or pH 7 buffer for at least 30 minutes before first use.

5. ഓപ്പറേഷൻ

5.1 കാലിബ്രേഷൻ

Calibration is essential for accurate measurements. The PH110 supports 1, 2, or 3 point calibration and automatically recognizes buffer solutions.

1. Turn on the meter by pressing the ഓൺ/ഓഫ് ബട്ടൺ.
2. Prepare fresh pH buffer solutions (e.g., pH 4, 7, and 10). These are sold separately.
3. അമർത്തിപ്പിടിക്കുക CAL button until 'CAL' appears on the display.
4. Immerse the electrode into the first buffer solution (e.g., pH 7). The meter will automatically recognize the buffer and calibrate. Wait for the reading to stabilize.
5. For 2 or 3 point calibration, rinse the electrode with distilled water and immerse it into the next buffer solution (e.g., pH 4, then pH 10). The meter will continue to calibrate automatically.
6. Ensure the display shows 'CAL' during the calibration process.

5.2 അളവ്

The flat surface electrode allows for versatile measurements.

1. After calibration, rinse the electrode with distilled water.

3. Allow the reading to stabilize on the display. The analog bargraph will indicate trends in acidity or alkalinity.
4. To switch between pH and temperature display modes, press the മോഡ് ബട്ടൺ.

6. പരിപാലനം

6.1 Electrode Refilling

The refillable electrode design allows for prolonged accuracy and lifespan.

1. When the reference solution depletes or accuracy declines, use the provided removal tools to access the reference junctions.
2. Carefully refill the electrode with the 1.5mL KCI solution.
3. Ensure the reference junctions are properly re-seated after refilling.

6.2 വൃത്തിയാക്കലും സംഭരണവും

• Always rinse the electrode with distilled water after each use to prevent contamination.
• The flat surface electrode is designed for easy cleaning. Gently wipe with a soft cloth if necessary.
• Store the electrode with its protective cap filled with electrode storage solution (or pH 7 buffer if storage solution is unavailable) to keep the sensor hydrated. Do not store dry.

7. പ്രശ്‌നപരിഹാരം

If the meter exhibits inaccurate readings or operational issues, consider the following:

• കൃത്യമല്ലാത്ത വായനകൾ: Recalibrate the meter using fresh buffer solutions. Ensure the electrode is clean and properly hydrated. Check if the reference solution in the electrode needs refilling.
• ഡിസ്പ്ലേ/പവർ പ്രശ്നങ്ങളില്ല: ബാറ്ററികൾ ശരിയായി ഇൻസ്റ്റാൾ ചെയ്തിട്ടുണ്ടെന്നും ആവശ്യത്തിന് ചാർജ് ഉണ്ടെന്നും ഉറപ്പാക്കുക. ആവശ്യമെങ്കിൽ ബാറ്ററികൾ മാറ്റിസ്ഥാപിക്കുക.
• മന്ദഗതിയിലുള്ള പ്രതികരണം: The electrode might be dry or contaminated. Clean and rehydrate the electrode, then recalibrate.
