8.3 Storage
Between uses, make sure the probe is dry and store it in ambient conditions. Rugged probes may be
stored with the shroud installed if the storage container is sufficiently large.
Section 9 Troubleshooting
Problem
Decreased probe performance
causes slow stabilization and
prevents accurate calibrations
or measurements.
Sample properties cause slow
stabilization or inaccurate
measurements.
Procedure problem causes
slow stabilization and prevents
accurate calibrations or
measurements.
10 English
Possible cause
The probe has mineral or sample
buildup on the electrodes.
The sample absorbs carbon
dioxide (CO
) from the air, which
2
forms carbonic acid and slowly
increases the conductivity in low
ionic strength (LIS) or high purity
samples.
An incorrect standard solution was
used or the standard solution is
contaminated.
Air bubbles are around or below
the probe tip.
The conductivity settings in the
meter are not correct.
Solution
Clean the probe. Refer to
Clean the probe
on page 8.
Use the LIS chamber for
LIS/high purity samples to
prevent CO
absorption.
2
Use the specified standard
solution of good quality.
Carefully tap or shake the
probe to remove air bubbles.
Make sure that the settings
for temperature correction,
reference temperature and
stability are correct.
