Cleaning The Block And Sensors - Decagon Devices AquaLab 4TE Operator's Manual

Purpose
Th e purpose for the cleaning procedure is to remove grease, dirt and
other soluble substances which can absorb/release water during veri-
fi cation, calibration, and/or sample testing. For a smooth and even
dew formation, it requires the mirror to be perfectly clean. If there
are any contaminants (e.g. fi ngerprints) on the mirror, the dew will
form unevenly and thus aff ect the accuracy of the reading.
When to Clean
Th e instrument should be cleaned if visual inspection indicates the
chamber is dirty or as instructed in the verifi cation fl owchart on
page 41.
