INSTALLATION

Note: After recalibration and/or reinstallation the nylon insulators

must be replaced with new ones to maintain durability.

The mounting stand temperature can vary over a wider range than the

air temperature. Temperature fluctuations of the pyrgeometer body

can produce offset signals. It is recommended to isolate the

pyrgeometer thermally from the mounting stand,

e.g. by placing it on its levelling screws. But keep an electric contact

with earth to lead off currents in the cable induced by lightning.
