O Open-Path Gas Analyzer
Avoid crashing the arms of the sensors together. The arms
of the analyzer should slide in between the claws of the
CSAT3A; the sonic head may need to be loosened and
repositioned to do this.
10. Tighten bolts and check that the analyzer is oriented vertically such
that the label is right-side-up and the upper arm (source) is directly
above the lower arm (detector).
11. If the assembly is not level, slightly loosen the bolt that holds the
mounting bracket on the leveling mount and adjust the assembly until
the leveling bubble on the top of the CSAT3A head is within the
bullseye. Retighten the bolt.
