2. Siting and setup
2.1
Siting
considerations
The
following
siting
considerations
must
be
addressed:
2.1.1
Compass
accuracy
The
WEATHERPAK
M
contains
an
electronic
compass
for
automatic
alignment
to
True
North.
To
prevent
erroneous
compass
readings,
install
the
WEATHERPAK
M
at
least
30
met
re
s
(99
feet)
laterally
from
large
vans,
buses,
cranes,
or
other
large
magnetic
objects.
(The
top
of
a
van
is
suitable,
but
next
to
it
is
not
an
ideal
location.
2.1.2
Proper
wind
measurement
Locate
the
WEATHERPAK
M
away
from
obstructions
such
as
trees
and
buildings.
The
distance
between
wind
sensors
and
the
nearest
obstruction
should
be
ten
times
the
height
of
the
obstruction.
