Additional Components on Vantage Pro Plus
UV and Solar Radiation Sensors
Each sensor has 3' (0.9 m) of cable. If you need to position the sun sensors away
from the rain collector side, use extension cables #7876 .
Note: Not all cables are compatible with your Vantage Pro system. To be sure they will work, order
Davis extension cables from your dealer or directly from Davis Instruments.
To upgrade your Vantage Pro to Vantage Pro Plus, see "Optional Sensors for
ISS" on page 28.
Components
Vantage Pro Plus also includes an
ultraviolet (UV) sensor and a solar
radiation sensor. These two sensors are
on the rain collector side of 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).
Once you have mounted the ISS in its
final location, use the bubble level on
each sensor as a guide to verify that the
sensor is level. (To adjust, tighten or
loosen the screws holding the sensor on
the shelf.)
