  • Immerse the tester up to the maximum immersion level in pH 6.86 buffer solution.
  • Allow the reading to stabilize and using a small screwdriver adjust the calibration trimmer to read 6.86.
  • Immerse the electrode in PH4.01 or PH9.18 the standard buffer solution of borax. Until the display shows  3.96-4.06PH or 9.13-9.23PH.
  • Calibration is now complete.
  • ALWAYS USE FRESH BUFFERS FOR CALIBRATION.
  •  Important  The instrument must be re-calibrated whenever.
  • The electrode or battery has been  replaced.
