4.2.1 Alignment to north
For the exact determination of wind- and brightness direction the WEATHER STATION COMPACT
WSC11 must be mounted in
north alignment
(geographic north).
The
hexagon socket screw
serves as
north marking (N)
Tool:
Hexagon socket wrench SW2mm
(socket wrench).
Procedure:
1. Detect a prominent object in the
surrounding area (tree, building
etc.) in north direction by means of
a compass.
2. Via the north marking (N) and an
imaginary north-south axis the
weather station is to be located on
the prominent object.
3. Align weather station.
The north marking must indicate to
the geographic north.
4. In case of match the weather
station is to be secured by an M4-
hexagon socket screw.
Attention:
The hexagon socket
screw is to be tightened
by max. 0.6Nm.
Remark:
With the north alignment by means of a compass, the local variation (deviation in direction of a
compass needle from the true north direction) by interfering magnetic fields, and magnetic field
influences by hardware and electric cable are to be considered.
