How to Calibrate the PH Meter?
The water quality pen should be calibrated before use, and the measurement accuracy will be higher.
1. Before calibration, put the pH 4.01/ 6.86/ 9.18 buffer powder into 250 ml of distilled water and stir well
2. Turn on the on/off button, and adjust to PH mode
3. Put the probe into PH4.01 reagent, press and hold the CAL/MODE button for 6 seconds, when the data does not flash, the screen show "CAL" the calibration is successful . The PH6.68/PH9.18 calibrate is the same way.
4. After each calibration, the probe should be cleaned and wiped clean before proceeding to the next reagent calibration
