Has the internal
solution been
replaced? Replace the internal solution
before each measurement.
If not, the internal solution
concentration will change and it
cause measurement error.
(
“How to clean the
electrode” (page 38))
Is there a sufficient
amount of internal
solution? Make sure that the surface of the
solution is just below the internal
solution fill port.
Was the standard
solution made using
pure water? Prepare the standard solution
using pure water. Preparing the
standard solution with water other
than pure water will cause
measurement errors.

18))
―
Is calibration
performed before
each measurement? Perform calibration before each
measurement.
(
“Calibration operation”
(page 19))
―
Is the electrode
temperature same
as measurement
place? Wait until the temperature of the
electrode becomes the
temperature of that place before
using the electrode.
―
Is the ion selective
membrane or liquid
junction dirty? Rinse the electrode.

electrode” (page 38))
Has the internal
solution
concentration
changed? Replace the internal solution
completely.
