Installing the Magellan Sensor Transmitter
Site Selection
Finding a suitable site for the sensor transmitter is important for getting
representative ambient measurements. The site should represent the
general area of interest.
The sensor transmitter should be installed in a location that is free from
turbulence caused by nearby objects, such as trees or buildings.
WARNING
: To protect personnel (and the device), a lightning rod should
be installed with the tip at least 40 inches (one meter) above the sensor
transmitter. The rod must be properly grounded, compliant with all local
applicable safety regulations.
North Alignment
The Magellan sensor has a built-in electronic compass for North
alignment.
The Magnetic Declination has been entered into the sensor for your
area. To change the magnetic declination, contact Columbia Weather
Systems for more information.
Installing the Mast
There are three acceptable methods for mounting the mast to a roof or
building structure: Sloped roof mounting, flat roof mounting or wall
mounting. See
Optional Sensor Mounting Hardware
for more
information.
Location
Do not attach the sensor transmitter to a radio transmitting mast or
tower.
Select a mounting location that will allow the sensor cable to be routed
away from other data cables to avoid interference. Never route sensor
cables in tall trees. Do not mount sensors close to power lines or
telephone lines. For normal roof mounting, the recommended minimum
distance from power or telephone lines is 25 ft. (8 m). Use extreme
caution when working close to power lines.
Mounting Method
Choose the appropriate mounting method for the installation and obtain
any necessary mounting hardware. If the mounting hardware is not
obtained from the factory, be certain to use metal parts which are plated
or galvanized to assure maximum longevity.
