3. Installing the NR-LITE
Mount the sensor so that no shadow will be cast on it at any time of day from
obstructions such as trees, buildings or the mast or structure on which it is
mounted. In the northern hemisphere the instrument is normally oriented
towards the South to avoid potential problems from shading. The downward
facing sensor is representative (99%) for a circular area having a radius of ten
times the height (10h).
To avoid shading effects and to promote spatial averaging the NR-LITE should
be mounted at least 1.5 m above the ground surface. It is recommended that
the NR-LITE be mounted to a separate vertical pipe at least 25’ from any other
mounting structures. PN 14264 mounting bracket is used to mount the NR-
LITE directly to a vertical pipe, or to a UT108 Tower Mounting Bracket and
Crossarm. Mount the sensor as follows:
1.
Attach PN 14264 mounting bracket to the vertical mounting pipe, or
UT018 crossarm using the hardware provided. The hole through PN
14264 has two different diameters to accommodate different models of
sensors. The NR-LITE mounts through the larger diameter hole that
extends half way through the bracket.
2.
Feed the sensor cable through the larger diameter hole in the mounting
bracket, followed by the mounting arm of the sensor. Tighten the two set
screws just enough to secure the mounting arm position, but loose enough
to be rotated.
Do not attempt to rotate the instrument using the sensor head or
you may damage the sensor – use the mounting arm only.
3.
Loosen the vertical adjustment screws on the back of the 14264 mounting
bracket. Adjust the sensor mounting arm horizontally and vertically until
the bubble level on the sensor head shows level. Tighten the adjustment
screws to secure the position.
