설정 및 교정

초기 준비

Before first use, ensure the meter's electrode is clean. If the electrode appears dry, soak it in distilled water for approximately 30 minutes to rehydrate it.

pH 교정

1. Prepare pH 4.00 and pH 7.00 calibration solutions. Ensure they are at room temperature.
2. Turn on the meter. Press the "pH CAL" button.
3. Immerse the electrode into the pH 7.00 solution. Wait for the reading to stabilize, then confirm calibration as per the meter's display instructions.
4. 증류수로 전극을 헹굽니다.
5. Immerse the electrode into the pH 4.00 solution. Wait for the reading to stabilize, then confirm calibration.
6. For higher pH measurements, an additional pH 10.00 calibration point may be available on the meter. Consult the meter's specific display prompts for multi-point calibration.

EC/TDS 교정

1. Prepare the 1413 µS/cm conductivity calibration solution.
2. Turn on the meter. Press the "EC CAL" button.
3. Immerse the electrode into the 1413 µS/cm solution. Wait for the reading to stabilize, then confirm calibration as per the meter's display instructions.
4. Rinse the electrode with distilled water after calibration.

작동 지침

Measuring pH, EC, and Temperature

1. Ensure the meter is properly calibrated.
2. 미터를 켭니다.
3. Immerse the electrode into the solution to be tested. Ensure the electrode is fully submerged.
4. Wait for the readings (pH, EC/PPM, Temperature) to stabilize on the display.
5. Press the "MODE" button to switch between EC and PPM display modes if applicable.
6. Press the "TEMP" button to switch between Celsius and Fahrenheit temperature units if applicable.
7. 판독값을 기록합니다.
8. Rinse the electrode with distilled water after each measurement.

Adjusting pH with YINMIK pH Down

YINMIK pH Down is formulated to safely lower the pH of hydroponic nutrient solutions. It features an all-natural formula, is designed not to damage pipes, and has no odor.

1. Step 1: Check pH: Use the YINMIK pH meter or pH test strips to determine the current pH of your nutrient solution.
2. Step 2: Add pH Down: Add 3-5 drops of YINMIK pH Down solution per gallon of nutrient solution. (A general recommendation is 1 ml of pH adjuster per gallon of nutrient solution.)
3. Step 3: Mix and Wait: Mix the solution well and wait 2-3 minutes to allow the pH to stabilize. Recheck the pH value.
4. Step 4: Repeat: Repeat steps 2 and 3 until your desired pH level is achieved.

유지

• 전극 청소 : Always rinse the electrode with distilled water before and after each use. For stubborn residues, soak the electrode in a specialized pH electrode cleaning solution for 15-30 minutes, then rinse thoroughly with distilled water.
• 저장: Store the pH meter with the electrode cap filled with a storage solution (or pH 7.00 buffer solution) to prevent the electrode from drying out. Do not store the electrode in distilled water, as this can deplete the reference electrolyte.
• 구경 측정: Recalibrate the meter regularly, especially if readings become inconsistent or after prolonged storage. Frequent use may require weekly or bi-weekly calibration to maintain accuracy.
• 배터리 교체: If the display dims, flickers, or the meter becomes unresponsive, replace the batteries according to the instructions provided with the device. Ensure correct polarity during installation.

문제 해결

• 부정확한 판독:
  • Ensure the meter is properly calibrated. Recalibrate if necessary.
  • Check if the electrode is clean. Clean it as described in the Maintenance section.
  • Verify the electrode is fully submerged in the solution.
  • s를 확인하십시오amp온도가 계측기의 작동 범위 내에 있습니다.
• 느린 응답 시간:
  • The electrode might be dry or dirty. Clean and rehydrate the electrode.
  • The electrode might be nearing the end of its lifespan and may require replacement.
• 계량기가 켜지지 않음:
  • 배터리 잔량을 확인하고 필요한 경우 교체하십시오.
  • 배터리가 올바른 극성에 맞게 삽입되었는지 확인하세요.
