Has the internal
solution been
replaced?
Replace the internal solution
before each measurement.
If not, the internal solution
concentration will change and it
will cause measurement error.
Is there a sufficient
amount of internal
solution?
Make sure that the surface of the
solution is just below the internal
solution fill port.
If it is not sufficient, fill the internal
solution sufficiently.
(
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.
