Anemometer setup
Apart from the anemometer,
the
WatchDog
Weather
Station comes fully assembled
and ready to mount. The
anemometer arm is attached
to the enclosure back plate
with
two
clamps.
After
positioning the arm, the
screws should be tightened to
secure it in place.
A plastic envelope containing
a screw and a star washer are
included with the station. The
star washer should be used
under the screw holding the
bottom anemometer clamp.
Once the arm is positioned,
the self
-
tapping screw should
be screwed into the arm
through the hole drilled in the clamp. These parts improve
resistance to electrostatic discharge.
Push the wind cups onto the bottom of the
shaft flush with the bottom of the assembly
and tighten the set screw. When released,
the cups should drop slightly. If the cups do
not spin freely, loosen the set screw and
lower the cups slightly. The gap between cup
hub and assembly should be about 1/16 inch.
Push the wind vane onto the top of the shaft
and
calibrate
(see
Calibrating
the
Anemometer p. 23 for calibration procedure).
