4. Produto acabadoview

The YINMIK YK-T4 is a versatile 4-in-1 meter designed for hydroponic applications. It features a large, clear display that can show multiple parameters simultaneously, such as pH, EC/PPM, and temperature, without the need for manual switching. The meter is equipped with dedicated calibration buttons for ease of use and has a replaceable electrode for extended service life.

5. Configuração

1. Instalação da bateria: Open the battery compartment (usually located at the top or back of the meter) and insert the required batteries, observing polarity. Close the compartment securely.
2. Enxágue inicial: Before first use, rinse the electrode with distilled or deionized water.
3. Prepare Electrode Cap: Ensure the sponge inside the electrode cap is moist with the provided pH Electrode Storage Solution. This prevents the electrode from drying out, which can affect accuracy and lifespan.

6. Instruções de operação

1. Ligar: Pressione o botão liga/desliga para ligar o medidor.
2. Modo de seleção: Use the 'MODE' button to cycle through different measurement displays (e.g., pH/EC/Temp, pH/PPM/Temp).
3. Faça a medição: Mergulhe o eletrodo no sample solution, ensuring the sensor is fully submerged. Gently stir the solution and wait for the reading to stabilize (typically a few seconds).
4. Registro de leitura: Read the values displayed on the screen.
5. Unidade de temperatura: Use the 'TEMP' button to switch between Celsius (°C) and Fahrenheit (°F) if applicable.
6. Desligar: Press the power button again to turn off the meter. Rinse the electrode with distilled water after each use and replace the cap with moist storage solution.

7. Calibração

Regular calibration is essential for accurate readings. Calibrate your meter at least once a month, or more frequently if used often, if readings are inconsistent, or after replacing the electrode.

7.1 Calibração de pH

1. Prepare two clean beakers with pH 4.00 and pH 7.00 calibration solutions.
2. Lave o eletrodo com água destilada e seque.
3. Immerse the electrode into the pH 7.00 solution. Press and hold the 'pH CAL' button until the display shows 'CAL' or a similar indication. The meter will automatically recognize the solution and calibrate. Wait for the reading to stabilize and confirm calibration (e.g., 'END' or 'PASS').
4. Enxágue o eletrodo novamente com água destilada.
5. Immerse the electrode into the pH 4.00 solution. Repeat the calibration process as with pH 7.00.
6. For advanced users, a third point (pH 10.00) may be used if available and required for your specific range.

7.2 EC Calibration

1. Prepare a clean beaker with 1413 µS/cm conductivity calibration solution.
2. Lave o eletrodo com água destilada e seque.
3. Immerse the electrode into the 1413 µS/cm solution. Press and hold the 'EC CAL' button until the display shows 'CAL' or a similar indication. The meter will automatically recognize the solution and calibrate. Wait for the reading to stabilize and confirm calibration.
4. Após a calibração, enxágue o eletrodo com água destilada.

8. Manutenção

8.1 Limpeza dos eletrodos

Over time, deposits can accumulate on the electrode, leading to inaccurate readings even after calibration. Regular cleaning is crucial.

1. Enxágue o eletrodo com água destilada.
2. Immerse the electrode in the provided Electrode Cleaning Solution for approximately 15-30 minutes. For stubborn deposits, a longer soak may be necessary.
3. Gently brush the electrode tip with a soft brush (e.g., a soft toothbrush) if visible deposits remain.
4. Rinse the electrode thoroughly with distilled water.
5. Perform a full calibration after cleaning to ensure accuracy.

8.2 Armazenamento de eletrodos

Proper storage is vital for extending the life of your electrode.

• Always rinse the electrode with distilled water after use.
• Ensure the sponge inside the electrode cap is kept moist with pH Electrode Storage Solution. Never store the electrode dry.
• Replace the electrode cap securely after each use.

8.3 Solution Storage

The calibration and cleaning solutions are provided with double-layer strong sealing tape to prevent leakage and contamination during transportation and storage. Ensure bottles are tightly sealed after use to maintain their integrity.

9. Solução De Problemas

• Leituras imprecisas:
  • Ensure the electrode is clean. Refer to Section 8.1.
  • Perform a full calibration. Refer to Section 7.
  • Check if the electrode is damaged or worn out. Replace if necessary.
  • Verifique se o sample temperature is within the meter's operating range.
• Medidor não liga:
  • Check battery installation and ensure batteries are not depleted. Replace if needed.
  • Ensure the battery compartment is dry and free of corrosion.
• Tempo de resposta lento:
  • The electrode may be dirty or dry. Clean and re-moisten the electrode.
  • O eletrodo pode estar se aproximando do fim de sua vida útil.
