2. Prekosyon sekirite

• Always handle the meter and electrodes with care to prevent damage.
• Do not immerse the main meter unit in water. The unit is IP54 water-resistant, but not submersible.
• Itilize sèlman adaptè pouvwa yo bay la.
• Kenbe solisyon kalibrasyon yo akamples away from children and pets. Follow safety data sheets (SDS) for handling specific chemicals.
• Ensure the meter is placed on a stable, level surface during operation.
• Dekonekte kouran an anvan ou netwaye oswa fè antretyen.

4. Konekte pouvwa: Plug the power adapter into the "DC 9V" port on the back of the meter, then connect it to a standard 120V AC 60Hz power outlet.
5. Premye pouvwa sou: Press the power button to turn on the meter. The LCD display should illuminate.

5. Operasyon Enstriksyon

5.1. Kalibrasyon

The EC820 meter features 1 to 4 points auto-calibration. Regular calibration ensures accurate measurements.

1. Prepare Solisyon yo: Use the provided 84 µS/cm, 1413 µS/cm, and 12.88 mS/cm calibration solutions. Ensure solutions are at room temperature.
2. Rense elektwòd la: Rinse the conductivity electrode thoroughly with distilled or deionized water before and after each measurement or calibration. Gently blot dry with a lint-free tissue.
3. Antre nan Mòd Kalibrasyon: With the meter on, press the CAL button. The display will show "CAL" and prompt for the first calibration point.
4. Kalibrasyon Premye Pwen: Immerse the electrode into the 1413 µS/cm standard solution. Wait for the reading to stabilize (indicated by a stable icon on the display). The meter will automatically recognize the solution. Press ANTRE pou konfime.
5. Subsequent Points (Optional): For higher accuracy, proceed with 84 µS/cm and 12.88 mS/cm solutions following the same procedure. The meter will guide you through the process.
6. Sòti Kalibrasyon: After completing desired calibration points, press the MEAS button to return to measurement mode.

Nòt: The meter has a self-diagnosis function to help identify and fix common calibration problems. Refer to the on-screen prompts.

5.2. Mezi

1. Rense elektwòd la: Rense elektwòd la ak dlo distile.
2. Elektwòd plonje: Plonje elektwòd la nan s laample solution, ensuring the sensor is fully submerged.
3. Wait for Stability: Allow the reading to stabilize. The stable reading icon will appear on the LCD.
4. Lekti Anrejistreman: Read the Conductivity (EC), TDS, Salinity, or Resistivity value displayed on the large LCD. Temperature will also be displayed simultaneously.
5. Chanje inite yo: Peze a INITE button to cycle through different measurement units (e.g., µS/cm, mS/cm, ppm, ppt).
6. Depo done: The meter supports GLP data management with 500 groups of data storage. Use the M+ / R-M buttons to store and recall data.
7. Ekspòtasyon Done: Connect the meter to a PC via the USB cable and use the provided PC-Link software (Windows-based system only) to export data.

6. Antretyen

• Netwayaj elektwòd:
  • Regularly rinse the electrode with distilled or deionized water.
  • For stubborn deposits, refer to the electrode's specific cleaning instructions. Generally, a mild detergent solution or a specific electrode cleaning solution can be used, followed by thorough rinsing.
  • Do not scratch or damage the platinum black sensor.
• Depo elektwòd:
  • Always store the conductivity electrode in its protective cap filled with a proper electrode storage solution (e.g., 3M KCl solution or Apera Instruments storage solution). Never store dry.
• Netwayaj Kontè: Wipe the main meter unit with a clean, damp twal. Pa sèvi ak pwodui netwayaj abrazif oswa solvang.
• Mizajou lojisyèl: Check the Apera Instruments website periodically for any software updates for the PC-Link software.
