6.1. PH Calibration

PH calibration is crucial for accurate readings. The video demonstrates the PH calibration process. You will need the provided PH buffer powders (4.00, 6.86, 9.18) and distilled water to prepare calibration solutions.

  1. Prepare the PH buffer solutions: Dissolve each PH buffer powder packet in 250ml of distilled water.
  2. Turn on the meter and immerse the electrode into the 6.86 pH buffer solution.
  3. Press and hold the 'TEMP/CAL' button until the display shows 'CAL'.
  4. The meter will automatically recognize the buffer solution and calibrate. Wait for the reading to stabilize and lock.

7. Understanding Your Readings

7.1. PH Value Interpretation

The pH scale ranges from 0 to 14, indicating the acidity or alkalinity of a solution. A pH of 7 is neutral. Values below 7 are acidic, and values above 7 are alkaline.

PH scale from 0 to 14, indicating acidic, neutral, and alkaline ranges, with examples of common substances at different pH levels.
Figure 6: PH Scale Reference. The scale ranges from 0 (Acidic) to 14 (Alkaline), with 7 being Neutral. Examples include Battery acid (0), Stomach acid (1), Vinegar (2-3), Orange juice (3-4), Tomato (4-5), Black coffee (5), Urine (6), Water (7), Sea water (8), Baking soda (9), Indigestion tablet (10), Ammonia solution (11), Soapy water (12), Bleach (13), and Drain cleaner (14).

7.2. TDS Value Interpretation

TDS (Total Dissolved Solids) measures the concentration of dissolved solid particles in water. The higher the TDS value, the more dissolved matter is present. The measurement unit is ppm (parts per million) or ppt (parts per thousand).

TDS Value (ppm)Purity Level
0 ~ 50ഉയർന്ന പരിശുദ്ധി
50 ~ 100ഉയർന്ന പരിശുദ്ധി
100 ~ 300Average purity
300 ~ 600Low purity
600 ~ 1000Lower purity

8. പരിപാലനം

8.1. Probe Care

The meter features a detachable probe design, allowing for easy replacement and maintenance. This helps prevent accidental probe damage and reduces long-term replacement costs.

  • Always keep the probe clean. Rinse it with distilled water before and after each use.
  • Store the probe with the protective cap on, ensuring the sponge inside the cap remains moist with a few drops of KCL solution or distilled water to prevent the electrode from drying out.
  • If the probe becomes damaged or its accuracy degrades significantly, it can be easily replaced.

8.2. ബാറ്ററി മാറ്റിസ്ഥാപിക്കൽ

When the display becomes dim or the readings are unstable, it's time to replace the batteries. Follow the battery installation steps in Section 5.1.

9. പ്രശ്‌നപരിഹാരം

  • കൃത്യമല്ലാത്ത വായനകൾ: Ensure the meter is properly calibrated. Recalibrate if necessary. Check if the probe is clean and free from residue.
  • അസ്ഥിരമായ വായനകൾ: This could indicate low battery power. Replace the batteries. Also, ensure the probe is fully immersed and the solution is not agitated.
  • ഡിസ്പ്ലേ ഇല്ല: ബാറ്ററി ഇൻസ്റ്റാളേഷൻ പരിശോധിച്ച് ബാറ്ററികൾ തീർന്നിട്ടില്ലെന്ന് ഉറപ്പാക്കുക.
  • മന്ദഗതിയിലുള്ള പ്രതികരണം: The probe might be dry or contaminated. Clean the probe and ensure it is properly hydrated before use.
