3.1 초기 준비

1. 풀다: Carefully remove the meter and all accessories from the packaging.
2. 전극 준비: 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. 교정

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. 솔루션 준비: pH 4.00, pH 7.00, pH 10.01 완충 용액을 각각 소량씩 깨끗한 비커에 붓습니다.
2. 전극 세척: 전극을 증류수로 헹군 후 깨끗한 티슈로 부드럽게 닦아 말리십시오.
3. pH 7.00으로 보정: 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. pH 4.00으로 보정: 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. pH 10.01으로 보정: 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. 마치다: After all three points are calibrated, rinse the electrode and replace the protective cap.

4.2 EC Calibration (1-Point)

1. 솔루션 준비: Pour a small amount of 1413 µS/cm conductivity calibration solution into a clean beaker.
2. 전극 세척: 전극을 증류수로 헹구고 부드럽게 닦아 말리십시오.
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. 마치다: Rinse the electrode and replace the protective cap.

5. 사용 설명서

5.1 측정하기

1. 켜기: 전원 버튼을 눌러 측정기를 켭니다.
2. 전극 세척: Rinse the electrode with distilled water before each measurement.
3. 침지 전극: 전극을 s에 담그세요ample solution, ensuring the sensor is fully submerged. Stir gently to remove air bubbles.
4. 디스플레이 읽기: 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. 기록 데이터: Note down the stable readings.
7. 헹궈서 보관하세요: After measurement, rinse the electrode thoroughly with distilled water and replace the protective cap with storage solution.

5.2 온도 단위 변환

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

6. 유지관리

6.1 Electrode Cleaning

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 전극 보관

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 배터리 교체

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. 문제 해결

• 부정확한 판독:
  • Ensure the meter is properly calibrated. Recalibrate if necessary.
  • Check if the electrode is clean and properly hydrated (soaked in storage solution).
  • samp온도가 계측기의 작동 범위 내에 있습니다.
  • Ensure calibration solutions are fresh and not expired.
• 디스플레이 없음/계기가 켜지지 않음:
  • Check battery installation and replace batteries if they are low or depleted.
• 느린 응답 시간:
  • The electrode may be dry or contaminated. Rehydrate the electrode in storage solution or clean it.
