3. Turn on the switch. Insert the pH meter into the measured liquid until the liquid is submerged to a slight immersion, allowing the solution to soak slightly above the immersion line
4. Gently stir until the displayed value is stable, then read the displayed value.
PH meter calibration:
1, Add 250ml water to one pack of 6.86 correction powder. And shake gently. Put tester to solution, it is accurate if the tester shows 6.8 value.
2, If the displayed value is deviated from 6.8
