5. Submit the information to the TEAM portal. Every time the tipping gauge is

calibrated submit the information on the Sensor Installation/Calibration Form to the

TEAM portal. If the tipping bucket needed to be sent out for calibration, the Sensor

Calibration Metadata Form can also be submitted using the instructions in Section 4.14.

4.17 Solar radiation (LI 200X)

Equipment/supplies needed:

• Pen/Pencil

• Small Allen wrench

• Replacement Solar Radiation sensor

• Blank Sensor Installation/Calibration Form

• Blank Sensor Calibration Metadata Form

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

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

operation to keep two sensors always operating in alternate schedules (see Figure 6 to get an idea

of how the calibration schedule should work). Follow the steps below to replace the solar

radiation sensor.

1. 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).

2. Remove the pyranometer from the leveling base. Using the thin Allen wrench (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

Installation/Calibration Form.

3. 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 screw on the side of the base (using the thin Allen wrench). REMOVE THE

PLASTIC COVER PROTECTING THE SENSOR (otherwise the data will be

useless!).

4. 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.

5. 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.
