TEAM Climate Monitoring Protocol 3.0

6.4.3 Solar radiation (LI 200X)

The Licor LI 200X should be sent out for calibration every 2 years. As with the temperature

sensor, however, send out for calibration one of the duplicates at the end of the first year of

operation to keep two sensors always operating in alternate schedules (see section 6.4.1 and

Figure 13).

Follow these steps to replace the solar radiation sensor (you will need to fill in the Sensor

Calibration Form).

Disconnect the pyranometer from the data logger: Open the enclosure to get access to the

data logger and disconnect the four cables coming from the pyranometer into the data logger

(usually one into 3H (or 4H), one into 3L (or 3H) and two grounds).

Remove the pyranometer from the leveling base: Using the thin hex key (that comes with the

pyranometer), free the pyranometer from the leveling base. Write down the Serial Number

(below the Model label on one side) and the date on the Sensor Calibration Form.

Install the replacement: Locate the replacement pyranometer in its housing making sure that

the cable is routed through the slot on one side. Secure the pyranometer by tightening the hex

screw on the side of the base (using the thin hex key). REMOVE THE PLASTIC COVER

PROTECTING THE SENSOR (otherwise the data will be useless!).

Connect the pyranometer to the data logger: Route and secure the cable through the leveling

arm and base until it reaches the enclosure. Route through the enclosure making sure there is

enough slack to connect to the data logger. Connect the cables to the terminals where the

replaced-to-be pyranometer used to be (use the cabling diagram for your site to match the color

cables and terminals). Secure the cables inside the enclosure using a grommet and leaving

enough slack so they are not tense.

Check the Leveling Base: Make sure the new pyranometer is leveled by checking the bubble in

the leveling base. Adjust if necessary using the protruding screws on the leveling base.

Record the information and submit to the TEAM portal: Write down the serial number of the

new sensor and the date and time it was installed on the Sensor Calibration Form. Submit the

information to the TEAM portal as soon as technically feasible. See section 6.1.4 for

instructions on uploading the Sensor Calibration Form.
