Has the composition
and the
concentration of the
standard solution
changed?
Is the amount of the
discharging internal
solution appropriate?
Solution
If the standard solution has
expired, replace it with a new one.
Use up the standard solution
within approximately 3 months
after opening the bottle. Do not
return the standard solution to its
bottle once it has come out of the
bottle.

Press the upper gray part of the
electrode cap.
If the internal solution is
discharged too much, it may
cause measurement errors or a
decrease in the response rate
during calibration.
