Glossary of Common Terms
LCD
―LCD‖ is an acronym for ‖Liquid Crystal Display‖. This is a common type of display screen
used in televisions, computers, watches, and digital clocks.
BAROMETER & BAROMETRIC PRESSURE
A barometer is a device that measures the pressure of the air pushing on it—this
measurement is called the barometric pressure. We don’t actually feel the barometric
pressure because the air pressure is pushing equally in every direction.
RELATIVE AIR PRESSURE
Relative air pressure is the same as the barometric pressure. The calculation of relative air
pressure is a combination of the absolute air pressure and the altitude.
ABSOLUTE AIR PRESSURE
Absolute air pressure is the actual air pressure on the barometer without regard to altitude.
INCHES OF MERCURY (inHg)
Inches of Mercury is the common unit of measurement for air pressure in the United States.
HECTOPASCALS (hPa)
Hectopascals are the common units of measurement for air pressure in the International
System (SI) of measurement. The hectopascal holds the same value
Important Note:
The Professional weather station includes a base station (receiver), a transmitter unit, one
wind direction sensor, one wind speed sensor, one rain gauge, USB cable and a PC software
package on CD-ROM.
An added feature of the Weather Station is the readout of all measured and displayed
time and weather data on a PC.

Set up Guide
Before placing and installing all components of the weather station at there final destination,
please set up the weather station with all parts being nearby for testing the correct function.
Setting up the base station and transmitter
1) Insert 2XAA 1,5V alkaline rechargeable batteries first into the battery compartment of the
remote sensor and immediately afterwards 3XAA 1,5V alkaline batteries in the base
station, observing the correct polarity. When battery is first inserted, the red LED light on
the remote sensor will be light up for 3-4 seconds. (If no LED light up or is lighted
permanently, make sure the battery is inserted the correct way or a proper reset is
happened)
2) When the base station is powered up, the LCD display activates for 3 seconds and after
the ―Beep‖, it begins measuring indoor temperature, humidity and air pressure. The unit
then enter the RF(Radio Frequency) state, where it receives data from the remote sensor.
RF (Radio Frequency) Receiving Mode
1. After power-on, the weather station enters RF receiving state for 180s
2. Base station receive the temperature, humidity, wind speed and rain data each 48s, receive
illuminance date each 60s. If there is no new effective signal from the sensor in constance
receiption failure in 10minutes, the outdoor temperature and humidity will display ―----‖. If base

station didn’t receive the signal in 240 minutes, the base station will start search and register
new sensor.
3. If the outdoor data lost or a battery change for the transmitter, press the reset button on the
solar power cabinet to re-send the signal and set the reregister on at display console to
register new transmitter.
4. Do not press any key before outdoor sensor data received, otherwise the outdoor sensor
learning mode will be terminated. When outdoor transmitter has been registered, the base
station will automatically switch to the normal display mode from which all further settings can
be performed by the user.
5. If there is no temperature reading in the base station, make sure the units are within range of
each other or repeat the battery installation procedure.
Note:
Commonly the radio communication between receiver and transmitter in the open field can
reach a distance of up to 330 feet providing that there are no interfering obstacles such as
buildings, trees, vehicles, high voltage lines, etc.
Radio interferences such as PC screens, radios or TV sets can, in bad cases, entirely cut off
radio communication. Please take this into consideration when choosing standing or mounting
locations.
Mounting the sensor
Important Notes:
On the edge of wind direction sensor, there are four alphabet letter of ―N‖,‖E‖,‖S‖and ―W‖
representing for the direction of North, East, South and West. Wind direction sensor has to be
adjusted so that the directions on the sensor are matching with your real location. Permanent
wind direction error will be introduced when the wind direction sensor is not positioned
correctly during installation.

Mounting the thermo-hygro sensor
Fix the whole set to a pole
same as rain sensor
with the two adjustable hoops.
The anemometer’s cable is connected
to the input on the wind direction
sensor.
The wind direction sensor’s cable is
connected to the input marked Wind on
the thermo-hygro sensor
The rain sensor’s cable is connected to
the input marked Rain on the solar
panel
The solar panel’s cable is connected to
the input marked Rain on the
thermo-hygro sensor.
The solar transmitter
The solar transmitter makes use of solar energy to power the instruments they are connected
to.
Note: It use AA size alkaline rechargeable batteries. For the solar transmitters to function
properly, make sure the solar receptors on the transmitters are exposed to sunlight and the
connectors of the connection cable are securely plugged in.
For best results, direct solar panel as follows:
Solar panel facing north if you reside in the southern hemisphere; Solar panel facing south if
you reside in the northern hemisphere.

Troubleshooting Guide
Problem
Solution
Wireless remote (outdoor unit) not
reporting in to console.
There are dashes (--) on the display
console.
Check the thermo-hygrometer-transmitter LED for
flashing. You must remove the radiation shield to view
the LED.
The outside sensor has an LED under the plastic, just
above the battery compartment. The LED will flash
every 48 seconds.
If the LED is not flashing every 48 seconds, Replace the
batteries in the outside thermo-hygrometer-transmitter.
If the batteries were recently replaced, check the polarity.
If the sensor is flashing every 48 seconds, proceed to the
next step.
There may be a temporary loss of communication due to
reception loss related to interference or other location
factors,
or the batteries may have been changed in the remote and
the console has not been reset. The solution may be as
simple as powering down and up the console.
1. Make sure you have fresh batteries in the
display console.
2. With the sensor array and console 10 feet
away from each other, remove the batteries

20
Problem
Solution
from the display console and wait 10
seconds. Put the batteries back in.
3. Do not touch any buttons for several
minutes.
4. The remote sensor search icon will
splash on the display. Wait several minutes
for this icon to turn off.
5. If the search icon turns off and the outdoor
temperature and humidity are still showing
dashes (--), the remote sensor is defective. If
the sensor properly syncs up, proceed to the
next step “How to prevent intermittent
wireless communication”
How to prevent intermittent wireless communication
issues: 1. Install a fresh set of batteries in the remote
sensor array and console. For cold weather
environments, install lithium batteries.
2. The maximum line of sight communication
range is 300’ but most users will get 100’ or
less due to environmental conditions.
Move the sensor and remote closer together.
3. If the sensor assembly is too close (less than
5’), move the sensor assembly away from
the display console.
4. Make sure the remote sensors are not
transmitting through solid metal like
aluminum siding (acts as an RF shield), or
earth barrier (down a hill).
5. Move the display console around electrical
noise generating devices, such as computers,
TVs and other wireless transmitters or
receivers.
6. Move the remote sensor to a higher location.
Move the remote sensor to a closer location.
Temperature sensor reads too high in the
day time.
Make sure the thermo-hygrometer is mounted in a
shaded area on the north facing wall.
Indoor and Outdoor Temperature do not
agree
1. Allow up to one hour for the sensors to stabilize
due to signal filtering. The indoor and outdoor
temperature sensors should agree within 4 °F
(the sensor accuracy is ± 2 °F).
2. Perform a temperature calibration (reference
