2. Pour each calibration powder (4.00, 6.86 and 9.18) into a container filled with water and stir until completely dissolved
3. Rinse the pH meter with clean water
4. Dip the pH meter into 6.86 solution, stirring slowly until the number on the pH meter is rather stable, then press the "CAL" button to show the number 6.86
5. The pH meter will show the number 6.86 blinking, wait until the blink stops, then the calibration for number 6.86 has been completed

Every pH meter sold has been calibrated, but it is recommended that the pH meter be recalibrated periodically to keep it accurate. Calibration solutions can be stored and used for several times
