M OUNTING THE S ENSOR A RRAY
The sensor array has been pre-assembled for easy installation. However, you
will still need to provide a solid mounting for the sensor array. Mounting
hardware has been included for the most common installations (see figures on
page 12 for instruction).
For roof mounting, and for ease of installation in other locations, we recom-
mend using the optional Mounting Tripod (contact Davis for information).
Please refer to the tripod manual for tripod installation instructions.
Note: If mounting on a roof, tower, or other elevated structure without the tripod, be sure to consider
the effects of wind loading and vibration and design the installation accordingly.
CAUTION: Any metal object can and may attract a lightning strike, including
your weather station or tripod. If lightning strikes your station or strikes some-
where nearby, the station's internal electronics may suffer anywhere between
little to extensive damage. The station itself has been designed with consider-
able surge protection, but to safeguard nearby equipment and structures, we
recommend following local recommendations on properly
grounding your
installation. For more information, contact your local lightning protection
authority and/or refer to the following articles:
