Does the aqueous solution of the lithium sulfur electrolyte lead to corrosion of the nickel electrode?
Take out the electrode and dry it, adjust the pH temperature compensation knob to the sample solution temperature, immerse the electrode in the sample solution, shake and rest it, and display the stable reading.
Remove the electrode, rinse and dry, then dip into pH6.86 or pH7.00 buffer solution. If the error is more than 0.02pH, repeat (1) and (2) steps until the correct pHs value is displayed until the adjustment knob is not required in the two standard solutions.
Remove the electrode, wash, dry, and immerse in second standard solutions. When the indicating value is stable, the instrument slope indicator is adjusted so that the instrument indication value is the pHs value of the second standard solutions.
The electrode is washed and dried and dipped into the pH6.86 or pH7.00 standard solution. The temperature compensating knob is placed at the temperature of the solution. When the indicating value is stable, the positioning knob is adjusted so that the value of the instrument is the pHs value of the standard solution.
