Compass Alignment
1. If the sensor transmitter is already mounted, loosen the fixing screw on the mounting adapter.
2. Use a compass to determine that the transducer heads are exactly in line with the compass and
that the arrow on the bottom of the transmitter points to north.
3. If wind direction is referenced to True North, adjust the north orientation of the sensor by the
magnetic declination for your area.
4. Tighten the fixing screw on the mounting adapter when done.
Once the sensor transmitter is aligned to north, the transmitter can be removed from the mounting
adapter without losing the north orientation.
Installing the Mast
See Optional Sensor Mounting Hardware for more information on sloped roof mounting, flat roof
mounting and wall mounting
Location
Do not attach the sensor transmitter to 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.
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 the necessary mounting
hardware. Refer to Section 4 for information on optional sensor mounting hardware and accessories
which are available from the factory.
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.
Secure the mast to the roof, using guy wires with sufficient tensile strength or to building wall using a wall-
mount hardware kit.
