HM ഡിജിറ്റൽ TDS-4 പോക്കറ്റ് വാട്ടർ ക്വാളിറ്റി ടെസ്റ്റർ ഇൻസ്ട്രക്ഷൻ മാനുവൽ

ആമുഖം

The HM Digital TDS-4 is a compact and convenient digital tool designed to measure the Total Dissolved Solids (TDS) in water. TDS refers to any salts, metals, or minerals dissolved in water. This meter provides an instant reading of your water's purity level, displayed in parts per million (ppm). It is suitable for various applications including drinking water quality checks, water filtration and purification systems, hydroponics, aquariums, and more.

പ്രധാന സവിശേഷതകൾ

• Measures Total Dissolved Solids (TDS) in parts per million (ppm).
• Equipped with Automatic Temperature Compensation (ATC) for accurate readings.
• Features a Hold Function to freeze measurements for easy viewing.
• Automatic shut-off after 10 minutes of non-use to conserve battery life.
• Compact, pen-style design for portability.

The HM Digital TDS-4 requires two LR44 batteries, which are included with the device. To install or replace batteries:

1. Unscrew the top cap of the meter.
2. Carefully remove the old batteries (if replacing).
3. Insert two new LR44 batteries, ensuring correct polarity.
4. Screw the top cap back on securely.

പ്രാരംഭ പരിശോധന

Before first use, inspect the meter for any visible damage. Ensure the protective cap is present and fits securely over the electrodes.

പ്രവർത്തന നിർദ്ദേശങ്ങൾ

അടിസ്ഥാന അളവെടുപ്പ് നടപടിക്രമം

Follow these steps to obtain an accurate TDS reading:

1. സംരക്ഷണ തൊപ്പി നീക്കം ചെയ്യുക: Gently pull off the cap covering the electrodes at the bottom of the meter.
2. Turn On the Meter: അമർത്തുക ഓൺ/ഓഫ് ബട്ടൺ. ഡിസ്പ്ലേ പ്രകാശിക്കും.
3. Immerse the Meter: മീറ്ററിന്റെ ഇലക്ട്രോഡ് അറ്റം വെള്ളത്തിൽ മുക്കുക.ample. Ensure the water level does not exceed the maximum immersion line (approximately 2 inches from the bottom).
4. വായന സ്ഥിരപ്പെടുത്തുക: Wait for the reading on the digital display to stabilize. This typically takes 10-30 seconds. Gently swirl the meter to dislodge any air bubbles that may be trapped around the electrodes, as these can affect accuracy.
5. Hold Reading (Optional): If you need to remove the meter from the water to view the reading, press the പിടിക്കുക button. The display will freeze the current measurement. Press പിടിക്കുക വായന റിലീസ് ചെയ്യാൻ വീണ്ടും.
6. റെക്കോർഡ് വായന: Note the TDS value displayed in ppm.
7. Turn Off the Meter: അമർത്തുക ഓൺ/ഓഫ് മീറ്റർ ഓഫ് ചെയ്യാനുള്ള ബട്ടൺ.
8. തൊപ്പി മാറ്റിസ്ഥാപിക്കുക: Always replace the protective cap after use to prevent damage to the electrodes.

ടിഡിഎസ് റീഡിംഗുകൾ മനസ്സിലാക്കൽ

TDS is measured in parts per million (ppm). A lower TDS value generally indicates purer water, as it contains fewer dissolved impurities. For example, distilled water typically reads 0 ppm, while tap water can vary significantly. The ideal TDS level depends on the specific application (e.g., drinking water, hydroponics, aquariums).

To ensure accurate readings, it is important to keep the electrodes clean. After each use, rinse the electrode area with clean, distilled water. Avoid touching the electrodes with your fingers, as oils and dirt can affect performance. If significant buildup occurs, gently clean with a soft brush and a mild detergent solution, then rinse thoroughly with distilled water.

സംഭരണം

Store the TDS-4 meter in a cool, dry place with the protective cap securely in place. Avoid exposing the meter to extreme temperatures or direct sunlight for prolonged periods.

കാലിബ്രേഷൻ

While the TDS-4 is factory-calibrated, periodic recalibration may be necessary to maintain accuracy, especially after extended use or if readings appear inconsistent. Calibration typically involves using a known TDS calibration solution (e.g., 342 ppm NaCl solution). Refer to the specific calibration instructions provided with your calibration solution or contact HM Digital support for guidance.

പൊതുവായ പ്രശ്നങ്ങളും പരിഹാരങ്ങളും

• Meter Does Not Turn On:
  ബാറ്ററികൾ ശരിയായി ഇൻസ്റ്റാൾ ചെയ്തിട്ടുണ്ടോ എന്നും ആവശ്യത്തിന് ചാർജ് ഉണ്ടോ എന്നും പരിശോധിക്കുക. ആവശ്യമെങ്കിൽ ബാറ്ററികൾ മാറ്റിസ്ഥാപിക്കുക.
• Inconsistent or Erratic Readings:
  Ensure the electrodes are clean. Rinse them with distilled water. Check for air bubbles around the electrodes during measurement and gently swirl to remove them. Recalibrate the meter if the issue persists.
• Reading Does Not Stabilize:
  Allow sufficient time (10-30 seconds) for the reading to stabilize. Ensure the meter is fully immersed up to the recommended level.
• Meter Dropped:
  If the meter has been dropped, it may require recalibration to ensure continued accuracy.
