DEPLOYMENT AND INSTALLATION

MOUNTING

Upward-facing: Mount the sensor to a solid surface with the nylon mounting screw provided. To accurately measure energy

flux density or photon flux density incident on a horizontal surface, the sensor must be level. An Apogee Instruments model

AL-200 leveling plate is recommended for this purpose. To facilitate mounting on a cross arm, an Apogee Instruments model

AM-110 mounting bracket is recommended.

Downward-facing: To facilitate mounting on a cross arm, and Apogee Instruments model AM-210 mounting bracket is

recommended.

To minimize azimuth error, the sensor should be mounted with the cable pointing toward true north in the northern

hemisphere or true south in the southern hemisphere. Azimuth error is typically less than 1 %, but it is easy to minimize by

proper cable orientation.

In addition to orienting the cable to point toward the nearest pole, the sensor should also be mounted such that

obstructions (e.g., weather station tripod/tower or other instrumentation) do not shade the sensor. Once mounted, the

green cap should be removed from the sensor. The green cap can be used as a protective covering for the sensor when it

is not in use.
