Troubleshooting
Is the temperature of
the solution being
stirred rising? A gradual rise in solution
temperature due to the magnetic
stirrer generating heat may cause
an apparent potential drift.
Reduce the influence of the
temperature changes by covering
the magnetic stirrer with heat
insulation such as polystyrene
foam or using a thermostatic bath.

―
Is measurement
being performed
while air bubbles are
on the ion selective
membrane? Shake the electrode to remove
any air bubbles remaining on the
ion selective membrane. If air
bubbles remain on the ion
selective membrane, it may result
in inaccurate measurement.
(
Note on page 35)
Is a solution at a
temperature outside
the measurement
temperature range
being measured? Adjust the temperature of the
solution so that it is within the
measurement temperature range
before measurement. If not, it
may cause measurement errors,
damages or deterioration to the
electrode.

“Specifications” (page 68))
―
Is the electrode
dirty? Rinse the electrode. A dirty
electrode will cause measurement
errors or a decrease in the
response rate during calibration.
