Measurement
④Start the third point calibration
Immerse the electrode in the pH 7 standard solution
until the liquid junction is fully submerged.
Immerse the electrode in the pH 4 standard solution
until the liquid junction is fully submerged.

To measurement
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
Press
Conrm that
the instantaneous value
is stable, then
press .
When changes
from the blinking state
to the lit state and
appears, calibration is
complete.
When performing the
second point calibration,
press .
Conrm that

When performing the
third point calibration,
press .
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.
When changes from the blinking state to
the lit state and appears, calibration is complete.
