For use with Davis’s Wireless, EZ-Mount, and Vantage Pro Weather Stations,
the Mounting Tripod simplifies installation. The tripod supports the sensor
array, and features an adjustable foot pad which enables mounting on any sur-
face: flat, inclined, or level. The anemometer extension tube can be used to ele-
vate the anemometer in installations where wind flow obstruction is a concern.

SSEMBLY
Follow the instructions below to assemble the tripod.
1. Unfold the tripod so the two foot pads which come pre-installed on the tripod legs are
flat on the ground.
2. Thread a hex nut almost all the way onto all six of the 5/16" bolts.
3. Insert one of the 5/16" bolts into the hole in vertical stop plate.
4. Insert the 5/16" bolt with vertical stop plate into one of the holes in the tripod's lower
bracket and thread a square nut onto the end of the bolt, on the inside of the bracket.
Do not thread the square nut too far up the bolt.
5. Repeat this procedure for the remaining 5/16" bolts. Place them into the holes in both
the top and bottom tripod brackets, threading a square nut on the end of each bolt.
Do not thread the square nuts too far up the bolts.
6. Insert the long extension tube into the tripod, sliding it through the brackets.
The vertical stop plate should keep the tube from sliding all the way
through.
7. Secure the extension tube by tightening the square and hex nuts on the 5/16" bolts
until the bolts hold the tube in place securely.

RIPOD
Mount the tripod with long extension tube on the desired surface, as shown
below. On the following pages are instructions for securing your sensor array
or ISS onto the long extension tube.
CAUTION: Any metal object may attract a lightning strike, including your weather station or tripod. If
lightning strikes your station or strikes somewhere nearby, the station's internal electronics may suffer
anywhere between little to extensive damage. The station itself has been designed with considerable
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:
✦ MIL-HDBK-419A: Grounding, Bonding, and Shielding for Electronic Equipments and Facili-
ties, 29 Dec 1987.
✦ National Fire Protection Association, 1997: Standard for Installation of Lightning Protection
Systems, 1997 ANSI/NFPA 780, National Fire Protection Association, Quincy, MA.

For Vantage Pro, the anemometer extension tube provided as part of the
mounting tripod will be used to support the ISS, which does not come on its
own pole. You can mount your ISS on this tube with both sides together or sep-
arate. For better access to the hardware securing the rain collector side, remove
the rain collector cone by rotating it counter-clockwise and lifting it off.
Mount your ISS on the anemometer extension tube as shown below, in either
Configuration A or Configuration B . Make sure the swaged end of the tube is
pointing downward as you secure the ISS to it.
Configuration A — Both Sides Together
Remember when mounting both sides together that whichever side of the ISS
is mounted first, the U-bolt from the opposite side ALSO must be placed
around the pole before you tighten anything. (If it is not, there is no way to
slide it in later.)

right.

points directly north.
3. Place the U-bolt pro-
vided with the tripod
around the tubes
where they overlap.
Secure saddle onto
U-bolt with flat
washers, lock

nuts as shown.
4. Tighten the hex nuts
quite firmly, until the
U-bolt begins to dent
