Possible cause
The sample temperature is
low, or there is a large
temperature difference
between samples.
Air bubbles are around or
below the probe tip.
The probe is not conditioned
for reducing samples.
The electrical connection
through the reference
junction is not sufficient.
An incorrect standard
solution was used or the
standard solution has
contamination.
Solution
Increase the sample temperature
or adjust the temperature of
different samples to be the same
(within 2 °C (3.6 °F)).
Carefully tap or shake the probe
to remove air bubbles.
Soak the probe in Reducing
solution for ORP electrodes for
3 to 10 minutes before sample
measurement.
Shake the probe in the solution
from side to side to refresh the
reference junction.
Use the specified standard
solution of good quality.
