Mounting the Tripod

The anemometer is factory calibrated to report the correct wind direction when the
anemometer arm is aiming north. If you cannot install the anemometer with the
arm aiming north, see your Vantage Pro2 Console Manual for instructions on how
to calibrate the console to display the correct wind direction.
1. Place the U-bolt for the anemometer around the pole so that its round end fits in
the top groove of the side of the rain collector side’s plastic mounting base. The
groove is right above two large holes.
2. While holding the mounting base of the rain collector against the pole, place the
two ends of the remaining U-bolt around the pole and through the two holes in
the base.
3. Slide the metal backing plate over the bolt ends as they stick out over the rain
collector base. Secure the metal backing plate with a lock washer and hex nut
on each of the bolt ends as shown previously.
Note: Do not tighten the hex nuts yet. Leave the hex nuts loose to swivel the ISS base on the pole.
4. The two ends of the anemometer’s U-bolt should now be pointing away from
the mounted rain collector side. Slide the anemometer’s mounting base over the
protruding bolt ends.
5. Place a flat washer, a lock washer and a hex nut on each of the bolt ends as
shown above. Do not tighten the nuts yet.
6. Raise the ISS unit to the desired height on the pole and swivel it so the
anemometer arm is pointing north.
7. Using an adjustable wrench or 7/16" wrench, tighten all four hex nuts until the
ISS is firmly fastened on the pole.
8. Re-attach the rain collector cone by setting the cone back on the base so its
latches slide downward into the latch openings on the base, then rotate the cone
clockwise.
Option 2: Installing ISS and Anemometer Separately
1. While holding the mounting base against the pole, place the two ends of a U-
bolt around the pole and through the two holes in the base.
2. Slide the metal backing plate over the bolt ends as they stick out toward the rain
collector cone. Secure the metal backing plate with a washer, a lock washer, and
a hex nut on each of the bolt ends. Do not tighten the nuts yet.
3. For the wireless ISS, swivel the ISS base so the solar panel is facing south (in
the Northern Hemisphere), or north (in the Southern Hemisphere).
4. Tighten the hex nuts using an adjustable wrench or 7/16" wrench.
5. Re-attach the rain collector cone.
6. Set the cone back on the base so its latches slide downward into the latch
openings on the base. Rotate the cone clockwise.
7. While holding the mounting base against the pole, place a U-bolt around the
pole and through the two holes in the base.
8. Place a flat washer, a lock washer and a hex nut on each of the bolt ends.
9. Swivel the anemometer until the arm is pointing north. The anemometer is
factory calibrated to report the correct wind direction when the anemometer arm
is aiming north. If you cannot install the anemometer with the arm aiming
