)

Light spectrum

waveband: 360 to 1120 nm (wavelengths where response

is 10% of maximum)

The black outer jacket of the cable is Santoprene

rubber. This

compound was chosen for its resistance to temperature extremes,

moisture, and UV degradation. However, this jacket will support

combustion in air. It is rated as slow burning when tested

according to U.L. 94 H.B. and will pass FMVSS302. Local fire

codes may preclude its use inside buildings.

7. Installation

If you are programming your datalogger with Short Cut, skip Section 7.3,

Wiring to the Datalogger, and Section 7.4, Programming. Short Cut does this

work for you. See Section 4, Quickstart, for a Short Cut tutorial.

7.1 Siting

The CS300 should be mounted such that no shadows or reflections are cast on

it by the tripod/tower or other sensors. The sensor should be mounted with the

cable pointing towards the nearest magnetic pole. For example, in the

Northern Hemisphere, point the cable toward the North Pole.

Mounting height is not critical for the accuracy of the measurement. However,

pyranometers mounted at heights of 3 m or less are easier to level and clean.
