proper grounding. A direct lightning strike to a metal pole can damage or destroy your home.
Warning: Installing your weather station in a high location may result in injury or death. Perform as much of
the initial check out and operation on the ground and inside a building or home. Only install the weather station on a
clear, dry, day.

Although the manual is comprehensive, much of the information contained may be intuitive. In addition, the manual
does not flow properly because the sections are organized by components.

4. Pre-Installation Checkout and Site Survey
4.1 Pre Installation Checkout
Before installing your weather station in the permanent location, we recommend operating the weather station for
one week in a temporary location with easy access. This will allow you to check out all of the functions, insure
proper operation and familiarize you with the weather station and calibration procedures.
4.2 Site Survey
Perform a site survey before installing the weather station. Consider the following:
1. You must clean the rain gauge every few months and change the batteries every 2-3 years. Provide easy
access to the weather station.
2. Avoid radiant heat transfer from buildings and structures. In general, install the sensor array at least 5’ from
any building, structure, ground, or roof top.
3. Avoid wind and rain obstructions. The rule of thumb is to install the sensor array at least four times the
distance of the height of the tallest obstruction. For example, if the building is 20’ tall and the mounting pole
is 6’ tall, install the sensor array 4 x (20 – 6)’ = 56’ away.
4. Mount the sensor array in direct sunlight for accurate temperature readings.
5. Installing the weather station over sprinkler systems or other unnatural vegetation may affect temperature
and humidity readings. We suggest mounting the sensor array over natural vegetation.
6. Wireless Range. Radio communication between receiver and transmitter in an open field can reach a
distance of up to 330 feet, providing there are no interfering obstacles such as buildings, trees, vehicles and
high voltage lines. Wireless signals will not penetrate metal buildings. Under most conditions, the
maximum wireless range is 100’.
7. Radio Interference. Computers, radios, televisions and other sources can interfere with radio
communications between the sensor array and console. Please take this into consideration when choosing
console or mounting locations. Make sure your display console is at least five feet away from any electronic
device to avoid interference.
