±2°F). Allow about 30 minutes for both sensors to stabilize.

Verify proper operation of the indoor and outdoor humidity. Verify the indoor and outdoor
humidity match closely with the console and sensor array in the same location (about
10'apart). The worst case sensor accuracy should be within 10% (the accuracy is ± 5%).
Allow about 30 minutes for both sensors to stabilize.

5 Weather Station Installation

5.1 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. This will also allow you to test the wireless range of the
weather station.

5.2 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 rechargeable batteries
every 2-3 years. Provide easy access to the rain gauge.
2. Avoid radiant heat transfer from buildings and structures. In general, install the
thermos-hygrometer in a shaded area on the north side of a structure.
3. Avoid wind obstructions. The rule of thumb is to install the anemometer 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 4 x (20 – 6)' = 56' away.
4. Wireless Range. The radio communication between receiver and transmitter in an open
field can reach a distance of up to 300 feet, providing there are no interfering obstacles
such as buildings, trees, vehicles, high voltage lines. Wireless signals will not penetrate
metal buildings. Under most conditions, the maximum wireless range is 100'.
5. Radio interference such as PCs, radios or TV sets can, in the worst case, entirely cut off
radio communication. 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.
