3. Configuração

3.1 Preparação Inicial

1. Descompacte: Carefully remove the meter and all accessories from the packaging.
2. Electrode Preparation: The electrode is shipped with a protective cap containing a small amount of storage solution. Before first use, remove the cap and rinse the electrode with distilled or deionized water.
3. Electrode Soaking: If the electrode appears dry, soak it in the provided pH Electrode Storage Solution for at least 30 minutes before calibration or measurement. This helps to rehydrate the glass bulb and ensure accurate readings.

4. Calibração

Regular calibration is essential for maintaining the accuracy of your YK-T4 meter. Always use fresh calibration solutions and follow the steps carefully.

4.1 pH Calibration (3-Point)

1. Preparar soluções: Pour small amounts of pH 4.00, pH 7.00, and pH 10.01 buffer solutions into separate clean beakers.
2. Enxágue o eletrodo: Enxágue o eletrodo com água destilada e seque-o delicadamente com um lenço de papel limpo.
3. Calibrate pH 7.00: Turn on the meter. Immerse the electrode into the pH 7.00 buffer solution. Press and hold the "TEMP / pH CAL" button until the display shows "CAL" or a flashing 7.00. The meter will automatically recognize the buffer and calibrate. Wait for the reading to stabilize and the calibration to complete (usually indicated by a stable reading or a confirmation message).
4. Calibrate pH 4.00: Rinse the electrode again. Immerse it into the pH 4.00 buffer solution. Press the "TEMP / pH CAL" button briefly to enter calibration mode for the next point. Wait for the reading to stabilize and calibration to complete.
5. Calibrate pH 10.01: Rinse the electrode. Immerse it into the pH 10.01 buffer solution. Press the "TEMP / pH CAL" button briefly. Wait for stabilization and completion.
6. Terminar: After all three points are calibrated, rinse the electrode and replace the protective cap.

4.2 EC Calibration (1-Point)

1. Preparar a solução: Pour a small amount of 1413 µS/cm conductivity calibration solution into a clean beaker.
2. Enxágue o eletrodo: Enxágue o eletrodo com água destilada e seque-o delicadamente com uma toalha.
3. Calibrate EC: Turn on the meter. Immerse the electrode into the 1413 µS/cm solution. Press and hold the "MODE / EC CAL" button until the display shows "CAL" or a flashing 1413. The meter will automatically recognize the buffer and calibrate. Wait for the reading to stabilize and the calibration to complete.
4. Terminar: Rinse the electrode and replace the protective cap.

5. Instruções de operação

5.1 Fazendo Medições

1. Ligar: Pressione o botão liga/desliga para ligar o medidor.
2. Enxágue o eletrodo: Rinse the electrode with distilled water before each measurement.
3. Eletrodo de imersão: Mergulhe o eletrodo no sample solution, ensuring the sensor is fully submerged. Stir gently to remove air bubbles.
4. Ler exibição: Wait for the readings to stabilize. The meter will display pH, EC/TDS, and Temperature simultaneously.
5. Switch Modes (if needed): Briefly press the "MODE / EC CAL" button to cycle through different display units for EC (µS/cm) or TDS (ppm).
6. Dados do registro: Note down the stable readings.
7. Enxágue e guarde: After measurement, rinse the electrode thoroughly with distilled water and replace the protective cap with storage solution.

5.2 Conversão de Unidades de Temperatura

To switch between Celsius (°C) and Fahrenheit (°F) temperature units, briefly press the "TEMP / pH CAL" button during normal operation.

6. Manutenção

6.1 Limpeza dos eletrodos

Rinse the electrode with distilled water after each use. If the electrode becomes dirty or contaminated, soak it in a mild cleaning solution (e.g., a dilute acid or enzyme cleaner, depending on the contaminant) for a short period, then rinse thoroughly with distilled water.

6.2 Armazenamento de eletrodos

Always store the electrode with its protective cap filled with pH Electrode Storage Solution. Never store the electrode dry or in distilled water, as this can damage the glass bulb and lead to inaccurate readings. If the storage solution in the cap evaporates, refill it with the provided solution.

6.3 Substituição da bateria

If the display becomes dim or the meter does not turn on, replace the batteries. Refer to the battery compartment for the correct battery type and orientation.

7. Solução De Problemas

• Leituras imprecisas:
  • Certifique-se de que o medidor esteja devidamente calibrado. Recalibre-o, se necessário.
  • Check if the electrode is clean and properly hydrated (soaked in storage solution).
  • Verifique se o sample temperature is within the meter's operating range.
  • Ensure calibration solutions are fresh and not expired.
• Sem visor/Medidor não liga:
  • Check battery installation and replace batteries if they are low or depleted.
• Tempo de resposta lento:
  • The electrode may be dry or contaminated. Rehydrate the electrode in storage solution or clean it.
