pH meter calibration:
1. Mix 6.86 grams of the correction powder with 250ML of water and gently shake it. Place the pen into the solution to test the pH value. If the display shows 6.8, the pen is accurate.
2. If the display deviates from 6.8, adjust the calibration potentiometer (the small hole behind) with a small screwdriver until the display value matches the pH value of the standard buffer solution at the ambient temperature. Be sure to keep the pen on the water surface when calibrating!
Notes:
In the following circumstances, the pH meter must be recalibrated:
After calibration, it has been used (or placed) for a long time.
The electrode is used particularly frequently.
