AquaLab TDL 6 CLEANING AND MAINTENANCE
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” in Section 7 for direc-
tions 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 sup-
port.foods@metergroup.com or 509-332-5601 for annual calibration.
