Optical sensor mount

The optional optical sensor mount places the sample volume at about 1.5 m, which complies with the WMO ‘Guide to Meteorological Instruments and Methods of Observation’, 7th Edition, Section 9.3.4.

The following are installation instructions for the optical sensor mount:

1. Install the mount on a concrete foundation with at least a 600 mm length, 600 mm width, and 600 mm depth. Ensure the ground consistency is not too loose and will be able to support the mount and concrete foundation.

2. Drill four 12 mm diameter holes to a depth of 77 mm at the locations indicated in Mounting footprint (in mm). The mount base can be used as a template.

3. Place washers and nuts on the ends of the wedge anchors supplied (to protect the threads during installation).

4. Hammer the wedge anchors into the holes until the start of the threads are below the surface.

5. Tighten the nuts until about 25 mm of thread protrudes above the surface.

6. Remove the washers and nuts from the protruding length screw and lower the mount into place.

7. Secure the mount with the washers and nuts.
