5.1 വായനകൾ മനസ്സിലാക്കൽ
pH ലെവലുകൾ
The pH scale ranges from 0 to 14, indicating acidity or alkalinity. 7.00 is neutral. Below 7.00 is acidic, above 7.00 is alkaline.
TDS in PPM
TDS (Total Dissolved Solids) indicates the amount of dissolved substances in water. Higher TDS generally means more impurities. The chart above provides a general guide for drinking water quality based on PPM:
- 0-50 ppm: Drinking Water
- 50-100 ppm: Filtration System
- 100-200 ppm: Hard Water
- 200-300 ppm: Marginally Acceptable
- 300-400 ppm: Ordinary Tap Water
- 400-500 ppm: Mineral Water
- 500+ ppm: Not Recommended for Drinking
ലവണാംശം അളക്കൽ
When the PPM value reaches 10,000, the meter seamlessly converts to PPT, ensuring precise measurements. Note: 1 ppt = 1000 ppm = 0.1%.
- Ideal pH Level for pools: 7.2-7.8 pH
- Ideal Salt Level for pools: 2700-3400 ppm
Hydroponics and EC
For hydroponics, the meter helps ensure optimal growth conditions:
- അനുയോജ്യമായ pH ശ്രേണി: 5.5-6.5
- Ideal PPM range: 800-1200
- Ideal EC range: 1.0-2.0 mS/cm

6. പരിപാലനം
6.1 ഇലക്ട്രോഡ് വൃത്തിയാക്കൽ
After each use, especially after calibration or testing different solutions, always rinse the electrode thoroughly with distilled or deionized water. Gently wipe the electrode with a soft cloth or tissue. Do not rub vigorously, as this can damage the sensitive glass bulb.
6.2 സംഭരണം
When not in use, ensure the electrode is kept moist. Store the meter with the protective cap filled with a small amount of electrode storage solution or pH 4.0 buffer solution. Never store the electrode dry or in distilled water, as this can shorten its lifespan.
6.3 ബാറ്ററി മാറ്റിസ്ഥാപിക്കൽ
The meter uses 3 x 1.5V LR44 button batteries. If the display shows a low battery indicator or the readings become unstable, replace the batteries as described in Section 4.1. Ensure the device is powered off before replacing batteries.
6.4 Electrode Replacement
The YG-9909 features replaceable electrodes. If the electrode becomes damaged or consistently provides inaccurate readings even after proper cleaning and calibration, it may need to be replaced. Contact customer support for information on obtaining replacement electrodes and detailed replacement instructions.
7. പ്രശ്നപരിഹാരം
- കൃത്യമല്ലാത്ത വായനകൾ: Ensure the electrode is clean and properly calibrated. Check battery levels.
- No Display/Flickering Display: ബാറ്ററി ഇൻസ്റ്റാളേഷനും ചാർജും പരിശോധിക്കുക. ആവശ്യമെങ്കിൽ ബാറ്ററികൾ മാറ്റിസ്ഥാപിക്കുക.
- മന്ദഗതിയിലുള്ള പ്രതികരണം: The electrode might be dirty or dry. Clean and re-moisten the electrode. Recalibration may also be needed.
- കാലിബ്രേഷൻ പരാജയം: Ensure calibration solutions are fresh and correctly prepared. Clean the electrode thoroughly before calibration.
If issues persist, refer to the detailed troubleshooting section in the full user manual or contact customer support.
8 ഉപയോക്തൃ നുറുങ്ങുകൾ
- Always rinse the electrode with distilled water before and after each measurement to prevent cross-contamination and ensure accuracy.
- For best results, allow the meter to stabilize in the solution for a few moments before recording the reading.
- Keep calibration solutions sealed and stored in a cool, dark place to maintain their integrity. Replace them periodically.
- Avoid touching the glass bulb of the electrode, as oils from your skin can affect its performance.
