AquaLab 6 CLEANING AND MAINTENANCE
the cleaning.
(e) Visually inspect the thermopile and optical sensor for clean-
liness. Clean again if necessary.
4. Additional Drying Time
(a) Visually inspect the sample chamber and sensors for con-
taminants, including moisture. If necessary, repeat the
cleaning process using new Kimwipes
R
.
(b) Let stand for five minutes to ensure the sample chamber
is dry.
6.4 Verification of Calibration
After you have cleaned the chamber and other parts of your AquaLab,
it is important to check the instrument performance in order to cor-
rect for any linear offset that may have occurred during the cleaning
process.
Before you check the instrument we recommend that you run a sam-
ple of the activated charcoal pellets provided in your AquaLab Clean-
ing Kit. This cleans the air inside the chamber, helping it come back
to a stable sampling environment.
Verify the linear offset against known verification standards accord-
ing to the procedure described in the next section. If a linear offset
has occurred, refer to adjust for linear offset section in Section 7 for
directions on how to correct for linear offset. If, after adjusting for
linear offset, your instrument is still not reading samples correctly, it
may be time for an annual factory calibration. Contact AquaLab at
support@aqualab.com or 509-332-5601 for annual calibration.
