O Open-Path Gas Analyzer and 3D Sonic Anemometer

Handle the IRGASON carefully. The optical source may

be damaged by rough handling, especially while the

analyzer is powered.

6. If the assembly is not level, slightly loosen the bolt that holds the

mounting bracket on the boom adapter and adjust the assembly until the

leveling bubble on top of the IRGASON block is within the bullseye.

Retighten the bolt.

7. Attach the EC100 enclosure to the mast, tripod leg, or other part of the

mounting structure. To do this, attach the EC100-enclosure mounting

bracket (pn 26604) to the pipe by loosely tightening the u-bolts around the

pipe. The u-bolts are found in the mesh pocket inside the EC100

enclosure. If the pipe does not run vertically (for example, if the enclosure

is being attached to a leg of a tripod), rotate the bracket to the side of the

pipe. The enclosure must hang upright. Make angle adjustments as

needed by loosening the four nuts and rotating the bracket plates relative

to one another. If the necessary angle cannot be achieved in the given

orientation, the four nuts may be removed and the top plate indexed by 90°

to allow the bracket to travel in the other direction (see FIGURE 6-2).

Once adjusted, tighten all the nuts. Finally, attach the EC100 enclosure to

the bracket by loosening the bolts on the back of the enclosure, hanging

the enclosure on the mounting bracket (it should slide into place and be

able to securely hang from the bracket), and tightening the bolts (see
