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.
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.
3. Quick Start Guide
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:

Version 1.6 ©Copyright 2019, Ambient LLC. All Rights Reserved. Page 4
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.
8. Visit Ambient Weather Mounting Solutions for assistance and ideas for mounting your
weather station:

5.3.1 Install Wind Vane
Reference Figure 2. (a) Locate and align the flat key on the wind vane shaft to the flat key on the wind
vane and push the vane on to the shaft. (b) tighten the set screw with a precision screw driver and
make sure the wind vane spins freely.
Note: You may need to back out the set screw first before sliding the vane onto the shaft.
Note: The wind vane shaft does not spin as freely as the wind cups. This is by design. The
dampening prevents the wind vane from spinning with the slightest breeze, which will result in
variable wind all of the time. The added resistance allows the wind vane to change direction with 2 –3
mph, providing a much better wind direction tracking.

5.3.5 Install Batteries
Reference Figure 6. Insert 2 x AA non-rechargeable batteries (not included) into the battery
compartment. The LED indicator on the back of the transmitter will turn on for four seconds, and then
flash once every 16 seconds (the sensor transmission update period).
(a)
(b)
Figure 6
Note: If the LED does not light up, or stays on permanently, make sure the battery polarity is
correct, or the batteries are fresh. Do not install the batteries backwards. You can permanently damage
the thermo-hygrometer.
Note: We recommend lithium batteries for cold weather climates, but alkaline batteries are
sufficient for most climates. We do not recommend rechargeable batteries. They have lower voltages,
do not operate well at wide temperature ranges, and do not last as long, resulting in poorer reception.

Version 1.6 ©Copyright 2019, Ambient LLC. All Rights Reserved. Page 9
5.3.6 Install Mounting Pole
Reference Figure 7. The mounting assembly includes two U-Bolts and a bracket that tightens around
a 1 to 2” diameter pole (not included) using the four U-Bolt nuts.
(a)
(b)
Figure 7
Use the bubble level next to the rain sensor to make sure the sensor array is completely level. If the
sensor array is not level, the rain gauge, UV and solar radiation sensors will not measure properly.
Note: If you cannot read the bubble level due to mounting constraints, place straddle a line or
ruler level across the top of the rain gauge for easier viewing.
5.3.6.1 Aligning the Wind Direction
Locate the North (N) Marker on the top of the sensor array. Align the marker to point North upon final
installation with a compass or GPS.

5.5 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and metal barriers. We
recommend the following best practices for trouble free wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet away from computer
monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 915 MHz devices and
communication is intermittent, try turning off these other devices for troubleshooting
purposes. You may need to relocate the transmitters or receivers to avoid intermittent
communication.
3. Line of Sight Rating. This device is rated at 300 feet line of sight (no interference, barriers or
walls) but typically you will get 100 feet maximum under most real-world installations,
which include passing through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum
siding. If you have metal siding, align the remote and console through a window to get a clear
line of sight.

6.4.1 Viewing Absolute vs. Relative Pressure
To switch between absolute and relative pressure, press and hold the [PRESSURE -] button for two
seconds.
Absolute pressure is the measured atmospheric pressure, and is a function of altitude, and to a lesser
extent, changes in weather conditions.
Absolute pressure is not corrected to sea-level conditions.
Relative pressure is corrected to sea-level conditions. For further discussion of relative pressure and
calibration, reference Section 6.4.4.
6.4.2 Rate of Change of Pressure Graph
The rate of change of pressure graphic is shown to the left of the barometric pressure and signifies the
difference between the daily average pressure and the 30 day average (in hPa).
