7.1 Siting
The CMP3 is usually installed horizontally, but can also be installed at any
angle including an inverted position. In all cases, it will measure the flux that is
incident on the surface that is parallel to the sensor surface.
Site the CMP3 to allow easy access for maintenance while ideally avoiding any
obstructions or reflections above the plane of the sensing element. It is
important to mount the CMP3 such that a shadow or reflection will not be cast
on it at any time (FIGURE
).
