When the measurement sample is known to be acid, perform two-point calibration with pH7 and pH4.
When it is known to be alkaline, perform two-point calibration with pH7 and pH9.
When the sample pH is not known, perform three-point calibration with pH4, pH7 and pH9.
Calibration
①Enter the calibration mode
②Start the rst point calibration
Immerse the electrode in the pH7 standard solution
until the liquid junction is fully submerged.

or
To third point calibration
③Start the second point calibration
Immerse the electrode in the pH4 standard solution
until the liquid junction is fully submerged.
Immerse the electrode in the pH9 standard solution
until the liquid junction is fully submerged.
※The calibration method is the same as first
and second point calibration.
④Start the third point calibration
