8. Mount the IRGASON temperature probe so that it measures temperature at
the same height as the sample volume of the IRGASON. To do this, first
attach the R.M. Young 41303-5A 6-Plate Solar Radiation Shield (pn 4020)
to the mast with the included u-bolt. Next, insert the end of the probe into
the hole on the bottom of the shield. Tighten the screws to hold the probe
in place. See FIGURE 6-4. For more detailed information about the
temperature probe installation and specifications, refer to the Model 107
Temperature Probe manual, which is available at www.campbellsci.com .
9. Remove the EC100- enclosure desiccant from the plastic bag and place it
in the mesh pocket of the enclosure. Attach the humidity indicator card to
the inside of the enclosure.

6.3 Wiring and Connections
FIGURE 6-5, FIGURE 6-6, and FIGURE 6-7 show the EC100 electronics
panel, the bottom of the EC100 enclosure, and sensor connections to the
EC100, respectively. Refer to these figures during wiring and connecting.
1. Find the thicker black cable coming from the block of the IRGASON.
This is the IRGASON gas-analyzer cable. Connect this cable to the
EC100 electronics by removing the black-rubber cable entry plug (pn
26224) on the bottom right of the EC100 enclosure. (This plug can be
stored in the mesh pocket of the enclosure). Next, insert the cable entry
plug that is attached to the cable into the vacant slot. Push the connector at
the end of the cable onto its mating connector (labeled Gas Analyzer) and
tighten the thumbscrews (see FIGURE 6-5). The gas analyzer cable is
approximately 3 meters in length.
