5. Naudojimo instrukcijos
5.1. Kalibravimas
The EC820 meter features 1 to 4 points auto-calibration. Regular calibration ensures accurate measurements.
- Paruoškite sprendimus: Use the provided 84 µS/cm, 1413 µS/cm, and 12.88 mS/cm calibration solutions. Ensure solutions are at room temperature.
- Skalavimo elektrodas: 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.
- Įjunkite kalibravimo režimą: With the meter on, press the CAL button. The display will show "CAL" and prompt for the first calibration point.
- Pirmojo taško kalibravimas: 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 ENTER patvirtinti.
- 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.
- Išeiti iš kalibravimo: After completing desired calibration points, press the PRIEMONĖS button to return to measurement mode.
Pastaba: The meter has a self-diagnosis function to help identify and fix common calibration problems. Refer to the on-screen prompts.
5.2. Matavimas
- Skalavimo elektrodas: Nuplaukite elektrodą distiliuotu vandeniu.
- Panardinamasis elektrodas: Panardinkite elektrodą įample solution, ensuring the sensor is fully submerged.
- Palaukite stabilumo: Allow the reading to stabilize. The stable reading icon will appear on the LCD.
- Įrašo skaitymas: Read the Conductivity (EC), TDS, Salinity, or Resistivity value displayed on the large LCD. Temperature will also be displayed simultaneously.
- Keisti vienetus: Paspauskite VIENETAS button to cycle through different measurement units (e.g., µS/cm, mS/cm, ppm, ppt).
- Duomenų saugykla: The meter supports GLP data management with 500 groups of data storage. Use the M+ / R-M buttons to store and recall data.
- Duomenų eksportavimas: 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. Priežiūra
- Elektrodų valymas:
- 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.
- Elektrodų laikymas:
- 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.
- Skaitiklio valymas: Wipe the main meter unit with a clean, damp audinys. Nenaudokite abrazyvinių valiklių ar tirpiklių.
- Programinės įrangos atnaujinimai: Check the Apera Instruments website periodically for any software updates for the PC-Link software.
