5.1. انشانکن

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. الیکٹروڈ کو کللا کریں: 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. کیلیبریشن موڈ درج کریں: With the meter on, press the CAL 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 داخل کریں۔ تصدیق کرنے کے لیے
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. کیلیبریشن سے باہر نکلیں: After completing desired calibration points, press the MEAS button to return to measurement mode.

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

6 دیکھ بھال

• الیکٹروڈ کی صفائی:
  • 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.
• الیکٹروڈ اسٹوریج:
  • 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.
• میٹر کی صفائی: Wipe the main meter unit with a clean, damp کپڑا کھرچنے والے کلینر یا سالوینٹس کا استعمال نہ کریں۔
• سافٹ ویئر اپ ڈیٹس: Check the Apera Instruments website periodically for any software updates for the PC-Link software.
