Calibration of the pH meter
1, the 250ml of distilled water or pure water can use calibration powder. PH electrodes immersed in pH value of mixed phosphate standard 6.86 buffer solution, and gently shake.
2, with yellow small screwdriver, facing pH pen behind the round hole, left and right rotation, you can adjust the correction potentiometer, until the display value and standard buffer solution at ambient temperature of pH value of 6.9 consistent.
3. Ibid. Insert the electrode into the standard buffer solution of pH4.00 potassium formate two potassium hydrogen phosphate.
4, after about two minutes. The display value should be within the allowable range of the error compared with the pH value of the buffer solution.
Do not stain the liquid, after the calibration with plastic wrap sealed, you can reuse, after correction, with clean water clean, if not often used, can be corrected once in 2-3 months!
