5. 교정

Calibration is essential for accurate readings. It is recommended to calibrate the meter at least once a month, or more frequently depending on usage and measurement accuracy requirements.

Figure 3: pH 4.00, pH 7.00, and 12.88 mS/cm conductivity calibration solutions are included for precise calibration.

5.1. pH 교정

1. 미터를 켜려면 버튼을 누르십시오. 켜짐/꺼짐 단추.
2. 를 누르세요 모드/CAL button repeatedly until the meter is in pH measurement mode.
3. Prepare pH 7.00 and pH 4.00 (or pH 10.01 if needed) calibration solutions.
4. Rinse the electrode with distilled water and immerse it into the pH 7.00 calibration solution. Stir gently and wait for the reading to stabilize.
5. 를 누르고 계세요 모드/CAL button for approximately 3 seconds until "CAL" appears on the display. The meter will automatically recognize the solution and calibrate. Once calibrated, the display will show "END" and return to measurement mode.
6. 증류수로 전극을 헹굽니다.
7. Immerse the electrode into the pH 4.00 calibration solution. Stir gently and wait for the reading to stabilize.
8. 를 누르고 계세요 모드/CAL button for approximately 3 seconds. The meter will automatically calibrate. Once calibrated, the display will show "END" and return to measurement mode.
9. Repeat for pH 10.01 solution if necessary.
10. Rinse the electrode with distilled water after calibration.

Figure 4: Calibration ensures accurate and consistent results for all parameters. Always calibrate pH 7.00 first.

5.2. EC/TDS/Salinity Calibration

1. 미터를 켭니다.
2. 를 누르세요 모드/CAL button repeatedly to switch to EC, TDS, or Salinity mode. Calibration for one of these modes will automatically calibrate the others.
3. Prepare the 12.88 mS/cm (12880 µS/cm) conductivity calibration solution.
4. Rinse the electrode with distilled water and immerse it into the 12.88 mS/cm calibration solution. Stir gently and wait for the reading to stabilize.
5. 를 누르고 계세요 모드/CAL button for approximately 3 seconds until "CAL" appears. The meter will automatically recognize the solution and calibrate. Once calibrated, the display will show "END" and return to measurement mode.
6. Rinse the electrode with distilled water after calibration.

7. 유지관리

7.1. 전극 청소

Regular cleaning of the electrode is crucial for accurate and stable readings. If the electrode appears dirty or readings become erratic, clean it as follows:

1. Rinse the electrode thoroughly with distilled or deionized water.
2. If stubborn contaminants are present, gently brush the electrode with a soft brush or soak it in a mild cleaning solution (e.g., a dilute detergent solution) for a few minutes.
3. Rinse again with distilled water and recalibrate the meter before next use.

7.2. 전극 보관

When not in use, always replace the protective cap. For long-term storage, ensure the electrode is kept moist. It is recommended to store the electrode in a pH electrode storage solution or a small amount of pH 7.00 buffer solution. Never store the electrode dry or in distilled water, as this can damage the sensor.

7.3. 배터리 교체

If the display becomes dim or the meter fails to power on, replace the batteries. Refer to section 4.1 for battery installation instructions. Ensure proper polarity and a secure seal after replacement.
