DAVIS Vantage Pro/Pro2 Wind Cup Replacement - Manual

Installing the Wind Cups
NOTE: DO NOT attempt to lubricate the wind cup shaft and
bearings or the wind vane shaft. Natural or synthetic lubricants
affect the normal operation of the anemometer by reducing the
components’ efficiency. They may also attract insects which can
interfere with moving parts.
Push the wind cups onto
the smaller of the two
stainless steel shafts at the
end of the arm.
Slide the wind cups up as far
as possible.
Use the Allen wrench
provided to tighten the set
screw on the side of the wind
cups. When you let go of the
wind cups, they should drop
slightly.
Spin the wind cups. If they
do not spin freely, loosen the
set screw and lower the cups
slightly. Repeat until the
wind cups spin freely.
