 and Vantage Pro Plus™

The Vantage Pro Integrated Sensor Suite (ISS) with the Fan-Aspirated Radia-
tion Shield uses a combination of fan-aspiration and shielding to minimize the 
effects of solar radiation-induced temperature error. 

Fan-Aspirated ISS Addendum Overview

This addendum provides additional information specific to the installation and 
use of the fan-aspirated radiation shield only, and is intended to be used in con-
junction with the “Integrated Sensor Suite Installation Manual.”

The table below shows the location of the information required to install and 
maintain your Fan-Aspirated ISS.
