PH meter calibration: 1, a pack of 6.86 correction powder against the 250ML water, and gently shake. Put the pen on detection of pH value of the solution, if 6.8 pen is. 2, if the display deviated from 6.8 with a small screwdriver adjustment potentiometer (behind the hole until the display matched with standard buffer solution at ambient temperature pH values. Don't leave the water when the correction pen! Note: In the following cases, pH must be recalibrated: After calibration has been used for a long time (or place); The use of special frequent electrode; The measurement accuracy is relatively high.
