5. ઓપરેટિંગ સૂચનાઓ
5.1. માપાંકન
The EC820 meter features 1 to 4 points auto-calibration. Regular calibration ensures accurate measurements.
- Prepare Solutions: Use the provided 84 µS/cm, 1413 µS/cm, and 12.88 mS/cm calibration solutions. Ensure solutions are at room temperature.
- Rinse Electrode: 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.
- Enter Calibration Mode: With the meter on, press the CAL button. The display will show "CAL" and prompt for the first calibration point.
- 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 દાખલ કરો ખાતરી કરવા માટે.
- 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.
- Exit Calibration: After completing desired calibration points, press the MEAS button to return to measurement mode.
નોંધ: The meter has a self-diagnosis function to help identify and fix common calibration problems. Refer to the on-screen prompts.
5.2. માપન
- Rinse Electrode: ઇલેક્ટ્રોડને નિસ્યંદિત પાણીથી ધોઈ નાખો.
- Immerse Electrode: ઇલેક્ટ્રોડને s માં બોળી દોample solution, ensuring the sensor is fully submerged.
- Wait for Stability: Allow the reading to stabilize. The stable reading icon will appear on the LCD.
- રેકોર્ડ વાંચન: Read the Conductivity (EC), TDS, Salinity, or Resistivity value displayed on the large LCD. Temperature will also be displayed simultaneously.
- એકમો બદલો: દબાવો UNIT button to cycle through different measurement units (e.g., µS/cm, mS/cm, ppm, ppt).
