5. സജ്ജീകരണം

5.1 ബാറ്ററി ഇൻസ്റ്റാളേഷൻ

The YY-400 requires 3 x 1.5V (LR44) button batteries (not included). To install or replace batteries:

1. Unscrew the top cap of the device.
2. Insert the 3 LR44 batteries according to the polarity markings.
3. Securely screw the top cap back on.

5.2 പ്രാരംഭ തയ്യാറെടുപ്പ്

Before first use, remove the protective cap from the probe. If the probe appears dry, rinse it with distilled water.

6. പ്രവർത്തന നിർദ്ദേശങ്ങൾ

6.1 ഒരു അളവ് എടുക്കുന്നു

1. അമർത്തുക ഓൺ/ഓഫ് മീറ്റർ ഓണാക്കാനുള്ള ബട്ടൺ.
2. Dip the electrode into the solution to be tested, ensuring the probe is fully submerged.
3. Gently stir the water and wait for the reading to stabilize on the LCD screen.
4. അമർത്തുക ഹോൾഡ്/ടെമ്പ് button to hold the current reading. Press again to release.
5. To switch between measurement modes (pH, ORP, H2, Temperature), press the മോഡ്/CAL ബട്ടൺ.
6. After use, rinse the electrode with distilled water and replace the protective cap.

6.2 വായനകൾ മനസ്സിലാക്കൽ

The device displays readings for:

• pH: Measures the acidity or alkalinity of the solution (0.01-14.00pH).
• ORP: Measures the Oxidation-Reduction Potential in millivolts (-999-1999mV).
• H2: Measures hydrogen concentration in ppb (parts per billion) or ppm (parts per million) (0-2400ppb, 0.001-2.400ppm).
• താപനില: Measures temperature in Celsius or Fahrenheit (0.1-60.0°C / 32.0-140.0°F).

7. കാലിബ്രേഷൻ

7.1 pH കാലിബ്രേഷൻ

Regular pH calibration ensures accuracy. Use the provided pH buffer powders (4.00, 6.86, 9.18) for calibration.

1. Prepare the buffer solutions by dissolving each powder packet in 250ml of distilled water.
2. Turn on the meter and select pH mode.
3. Dip the electrode into the 6.86 pH buffer solution.
4. അമർത്തിപ്പിടിക്കുക മോഡ്/CAL button until the display shows 'CAL'. Release the button.
5. The meter will automatically recognize the buffer and calibrate. Wait for the reading to stabilize and the 'CAL' indicator to disappear.
6. വാറ്റിയെടുത്ത വെള്ളം ഉപയോഗിച്ച് ഇലക്ട്രോഡ് കഴുകുക.
7. Repeat the process for pH 4.00 and pH 9.18 buffer solutions, calibrating from lower to higher pH values.

8. പരിപാലനം

8.1 ഇലക്ട്രോഡ് വൃത്തിയാക്കൽ

After each use, rinse the electrode thoroughly with distilled water to remove any residue. Do not use abrasive materials or harsh chemicals.

8.2 സംഭരണം

Always replace the protective cap on the electrode when not in use. Store the meter in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the electrode is kept moist by adding a few drops of electrode storage solution or pH 4.00 buffer solution to the cap.
