solution, and then put the pH electrode into the pH standard buffer solution.
After the actual measurement value is stable, press [ENT] to confirm the
calibration and return to the menu interface.
pH 2-point calibration: Select 2 points for calibration point and press [ENT]
to enter the calibration point selection interface. You can choose from 6
types of calibration point combinations: 4.00 / 6.86, 6.86 / 9.18, 4.00 / 9.18,
4.01 / 7.00, 7.00 / 10.01, 4.01 / 10.01. Press [ENT] to confirm the selected
calibration point and enter the first point interface of pH 2-point calibration.
Put the pH electrode into the first pH standard buffer solution. After the
actual measurement value is stable, press [ENT] to confirm the calibration
and enter the second point interface of pH 2-point calibration. Put the pH
electrode into the second pH standard buffer solution. After the actual
measurement value is stable, press [ENT] to confirm the calibration and
return to the menu interface.
pH 3-point calibration: Select 3 points for calibration point and press [ENT]
to enter the calibration point selection interface. You can choose from two
types of calibration point combinations: 4.00 / 6.86 / 9.18, 4.01 / 7.00 /
10.01. Press [ENT] to confirm the selected calibration point and enter the
first point interface of pH 3-point calibration. Put the pH electrode into the
first pH standard buffer solution. After the actual measurement value is
stable, press the [ENT] to confirm the calibration and enter the second
point interface of pH 3-point calibration. Put the pH electrode into the
second pH standard buffer solution. After the actual measurement value is
stable, press the [ENT] to confirm the calibration and enter the third point
interface of pH 3-point calibration. After the actual measurement value is
stable, press [ENT] to confirm the calibration and return to the menu
interface.
