6.3.1 Connecting the EC150 Gas Analyzer Head
1. Remove the black rubber cable entry plug (pn 26224) that is located on the
bottom right of the EC100 enclosure labeled Cable 3. (This plug can be
stored in the mesh pocket of the enclosure.)
2. Insert the cable entry plug that is attached to the large cable of the EC150
gas analyzer head into the vacant slot.
3. Push the connector at the end of the cable onto its mating connector
(labeled Gas Analyzer) and tighten the thumbscrews (see FIGURE 6-12).
The EC150 gas analyzer cable is approximately 3.0 m (10.0 ft) in length.
6.3.2 Connect the CSAT3A Sonic Head
Skip the following two steps if not using a CSAT3A.
1. Similar to connecting the gas analyzer head, remove the black rubber cable
entry plug found on the bottom left of the EC100 enclosure.
2. Insert the cable entry plug on the CSAT3A cable into the slot and connect
the male end to the female connector labeled Sonic Anemometer on the
EC100 electronics (see FIGURE 6-12).
Unlike previous models of the CSAT3 3D sonic anemometer, the
CSAT3A sonic head and the EC150 gas analyzer head have
embedded calibration information. This means that any CSAT3A
and any EC150 may be used with any EC100.
