2. Тэхніка бяспекі

• Заўсёды асцярожна звяртайцеся з глюкометрам і электродамі, каб пазбегнуць пашкоджанняў.
• Do not immerse the main meter unit in water. The unit is IP54 water-resistant, but not submersible.
• Выкарыстоўвайце толькі адаптар сілкавання, які ўваходзіць у камплект.
• Keep calibration solutions and samples 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.
• Адключыце электрычнасць перад чысткай або тэхнічным абслугоўваннем.

5. Інструкцыя па эксплуатацыі

5.1. Каліброўка

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

1. Prepare Solutions: Use the provided 84 µS/cm, 1413 µS/cm, and 12.88 mS/cm calibration solutions. Ensure solutions are at room temperature.
2. Прамыўны электрод: 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. Увайдзіце ў рэжым каліброўкі: With the meter on, press the КАЛ button. The display will show "CAL" and prompt for the first calibration point.
4. First Point Calibration: 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 УВОД каб пацвердзіць.
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. Exit Calibration: After completing desired calibration points, press the ВЫМЯР button to return to measurement mode.

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

5.2. Вымярэнне

1. Прамыўны электрод: Прамыйце электрод дыстыляванай вадой.
2. Апускальны электрод: Апусціце электрод у sample 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. Record Reading: Read the Conductivity (EC), TDS, Salinity, or Resistivity value displayed on the large LCD. Temperature will also be displayed simultaneously.
5. Змяніць адзінкі: Націсніце АДЗІНКА button to cycle through different measurement units (e.g., µS/cm, mS/cm, ppm, ppt).
6. Захоўванне дадзеных: The meter supports GLP data management with 500 groups of data storage. Use the M+ / R-M buttons to store and recall data.
7. Экспарт дадзеных: 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. Тэхнічнае абслугоўванне

• Ачыстка электродаў:
  • 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.
• Захоўванне электродаў:
  • 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.
• Meter Cleaning: Wipe the main meter unit with a clean, damp тканіна. Не выкарыстоўвайце абразіўныя ачышчальнікі або растваральнікі.
• Абнаўленні праграмнага забеспячэння: Check the Apera Instruments website periodically for any software updates for the PC-Link software.
