① Enter the measurement mode
When the measurement sample is known to be acidic, perform two-point calibration with pH 7 and pH 4. When it is known to be alkaline, perform two-point calibration with pH 7 and pH 9. When the sample pH is not known, perform three-point calibration with pH 4, pH 7 and pH 9. Calibration
To measurement
Immerse the electrode in the pH 9 standard solution until the liquid junction is fully submerged. ※The calibration method is the same as first and second point calibration.
Measurement
Con�rm that the instantaneous value is stable, then press .
