PH meter calibration:
1. Mix 6.66 grams of calibration powder with 250 ML of water, and shake gently. Place the pen to measure the pH value of the solution; if it shows 6.8, the pen is accurate.
2. If the display shows a deviation of 6.8, use a small screwdriver to adjust the potentiometer (the small hole on the back) until the displayed value matches the pH value of the standard buffer solution at ambient temperature. Do not remove the probe from the water surface during adjustment!
Precautions:
The pH meter must be recalibrated under the following conditions:
It has been used (or placed) for a long time after calibration;
Electrodes are used extremely frequently;
The measurement accuracy requirements are quite high.
