3.2.2 Mounting the KH20 Sensor
Mount the KH20 sensor head as follows:
1. Attach the 20 inch long mounting boom to the KH20.
2. Mount a crossarm onto a tripod or tower.
3. Mount the 12 inch long pipe (CSI p/n 18048) to a crossarm via 1” x 3/4”
Nu-rail (CSI p/n 1049).
4. Mount the KH20 onto the 12” long pipe using a 3/4” x 3/4” Nu-rail (CSI
p/n 1017). Mount the KH20 such that the source tube, the longer of the
two tubes, is positioned on top, as shown in Figure 1. Gather any loose
cables and tie them up, using cable ties, onto the tripod or tower mast.

3.2.3 Mounting the Electronics Box
Mount the electronics box as follows:
1. First, remove the front cover of the rain shield by loosening the two pan-
head screws on the bottom front of the rain shield, and then pushing the
cover all the way up, and sliding it out.
It will be difficult to mount the rain shield to a mast with the
front cover on, since the 1/2 inch nut holding the bottom U-bolt
is located inside the rain shield. NOTE
