Installing
CAUTION: The reflector plate and the waterproof film found in the wind channel of
the WeatherStation Instrument are essential to its operation (see Figure 3). Be
careful not to scratch the plate, puncture the film, or damage them in any way.
CAUTION: The WeatherStation Instrument must be installed upright and
vertically—NOT tilted to one side. If the WeatherStation Instrument is tilted from
the horizontal plane, it may introduce an error in the compass and wind readings.
CAUTION: To accurately measure the wind direction and vehicle/boat heading,
the alignment indentation on the WeatherStation Instrument must be pointed
correctly.
• Moving vehicle/boat—The alignment indentation must point forward and be
parallel to the centerline of the vehicle/boat.
• Stationary surface—It is recommended that the alignment indentation point
toward true north.
CAUTION: Do not tighten or align the WeatherStation Instrument by rotating the
upper cap. Turning may sever internal connections and void the warranty. Grasp
the lower housing below the reflector plate. Hand tighten only.
CAUTION: If you use a thread lock, use teflon pipe-thread tape. Do not use a
liquid thread lock as it may weaken the plastic, causing it to swell and crack.
