4. സജ്ജീകരണവും കാലിബ്രേഷനും

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 പ്രാരംഭ തയ്യാറെടുപ്പ്

1. ഇലക്ട്രോഡിൽ നിന്ന് സംരക്ഷണ തൊപ്പി നീക്കം ചെയ്യുക.
2. വാറ്റിയെടുത്ത അല്ലെങ്കിൽ ഡയോണൈസ് ചെയ്ത വെള്ളത്തിൽ ഇലക്ട്രോഡ് കഴുകുക.
3. Gently blot dry with a clean tissue. Do not rub.

4.2 കാലിബ്രേഷൻ പ്രക്രിയ

1. pH മീറ്റർ ഓണാക്കുക.
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. വാറ്റിയെടുത്ത വെള്ളം ഉപയോഗിച്ച് ഇലക്ട്രോഡ് കഴുകി ഉണക്കുക.
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. വാറ്റിയെടുത്ത വെള്ളം ഉപയോഗിച്ച് ഇലക്ട്രോഡ് കഴുകി ഉണക്കുക.
8. Your meter is now calibrated and ready for use.

കുറിപ്പ്: 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.

6. പരിപാലനവും സംഭരണവും

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

6.1 ഇലക്ട്രോഡ് വൃത്തിയാക്കൽ

• Always rinse the electrode with distilled or deionized water before and after each use.
• 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 സംഭരണം

• 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.
• മീറ്റർ തണുത്തതും വരണ്ടതുമായ സ്ഥലത്ത് സൂക്ഷിക്കുക, നേരിട്ടുള്ള സൂര്യപ്രകാശവും ഉയർന്ന താപനിലയും ഏൽക്കാത്ത സ്ഥലത്ത് സൂക്ഷിക്കുക.

7. പ്രശ്‌നപരിഹാരം

• കൃത്യമല്ലാത്തതോ അസ്ഥിരമായതോ ആയ വായനകൾ:
  • 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.
  • എസ് ഉറപ്പാക്കുകample temperature is within the meter's operating range.
• Meter Does Not Turn On:
