    2 Warnings and Cautions Warning: Any metal object may attract a lightning strike, including your weather station mounting pole. Never install the weather station in a storm. Warning: If you are mounting the weather station to a house or structure, consult a licensed electrician for proper grounding. A direct lightning strike to a metal pole can damage or destroy your home.

    5.Set up Guide 5.1 Pre Installation Checkout To complete assembly you will need a Philips screwdriver (size PH0) and a wrench (size M5; included in package). Before installing the weather station on the place of operation, we recommend placing the weather station at a temporary location with easy access for one week.

    obstruction. For example, if the building is 20’ or 6.10m tall and the mounting pole is 6’ or 1.83m tall, install the sensor array 4 x (20 – 6)’ = 56’ or 4 x (6.1-1.83)=17.08m away. 3. Installing the weather station over sprinkler systems or other unnatural vegetation may affect temperature and humidity readings.

  • Page 12: Install Wind Vane

    5.3.2 Install wind vane Push the wind vane onto the shaft on the top side of the sensor package, until it goes no further, tighten the set screw, with a Philips screwdriver (size PH0). Make sure the wind vane can rotate freely. The wind vane’s movement has a small amount of friction, which is helpful in providing steady wind direction measurements.
