      How to perform a full pH probe calibration on an Edge 100 and 200

      Learn how to use the pH full calibration function for Edge 100 and 200 controllers.

      A full calibration is needed:

      1) to confirm that probe is still tracking

      2) if you are constantly calibrating a full calibration will help completely calibrate the probe.


      Items needed:

      1) pH probe connected to controller

      2) Buffer solution pH 7 and Ph 4 or Ph9

      3) Glass of water. 

       

       

      Steps: 

      1. Make sure the pH probe is connected to controller
      2. Isolate controller from flow
      3. Unscrew pH probe from probe housing
      4. Wash probe in water
      5. Shake off probe
      6. Go to calibration menu click on Ph calibration click on full calibration
      7. Immerse probe into buffer solution pH 7
      8. Wait till the number under reading stabilizes 
      9. Calibrate probe under P1
      10. Wash probe in water
      11. Shake off probe 
      12. Immerse probe into buffer solution pH 4 or pH 9 
      13. Wait till the number under reading stabilizes 
      14. Calibrate probe under P2
      15. Save
      16. Wash probe in clean water
      17. Shake off probe
      18. Replace probe into probe container 
      19. Turn on flow to controller
      20. Wait a few hours to manual test and make sure controller matches

      Troubleshooting: If when the probe is immersed in the buffer solution the reading on the calibration screen does not match the buffer solution, your probe needs to be replaced. 

      If the pH still needs to be calibrated multiple times after full calibration your probe needs to be replaced.
