The Vantage Pro Integrated Sensor Suite (ISS) with the Fan-Aspirated Radiation Shield uses a combination of fan-aspiration and passive 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 conjunction 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.

Additional Components on Vantage Pro Plus
Vantage Pro Plus includes an ultravio-
let (UV) sensor and a solar radiation
sensor . These two sensors are mounted
next to the rain collector on your ISS.
Note: Please make every effort when handling your
ISS not to touch the small white diffusers on
top of the UV and solar radiation sensors. Oil
from the skin will reduce their sensitivity . Clean
the diffusers using ethyl alcohol on a soft cloth
(NOT rubbing alcohol). The solar radiation
sensor may also be cleaned with soap and
water.

Page 4 Fan-Aspirated Radiation Shield
Preparing the ISS and Radiation Shield
The radiation shield must be partially disassembled in order to make necessary
cable connections, and to install batteries in the solar-powered wireless ISS.
The ISS sensors are connected by cables to the Sensor Interface Module (SIM),
located inside the radiation shield. The SIM contains electronics that measure
and store weather values for transmission to the console via cable or radio
waves. The radiation shield’s white plastic plates protect the SIM from sun and
other sources of radiated and reflected heat, and from precipitation.
The following tasks are performed while the radiation shield is disassembled:
✦
Check the rain, solar radiation, and UV cable connections to the SIM sensor
✦
Connect the anemometer sensor cable to the SIM
✦
Connect the console cable to the SIM (cabled versions only)
✦
Make power connections to the ISS
✦
Change the Davis Talk ID for wireless communication, if necessary
✦
Verify that your console is receiving and displaying data
✦
Power and test the fan
Opening the Radiation Shield
Open up the radiation shield by separating the top and bottom parts as shown
in the following illustrations.
1.
Turn the rain collector side of the ISS upside down.
2.
Remove the three wing nuts, lock washers and flat washers located on the
underside of the radiation shield.
