3.5 Sensors Operation Verification
The following steps verify proper operation of the sensors prior to installing
the sensor array.
1. Verify Wind Speed. Rotate the wind cups manually or with a constant speed
fan. Verify the wind speed is not reading 0.0.
13
2. Verify In/Outdoor Temperature. Verify the indoor and outdoor temperature
match closely with the console and sensors in the same location (about 5 to
10′ (1.5 to 3 meters) apart). The sensors should be within 4°F /2°C (the
accuracy is ± 2°F/1°C). Allow about 30 minutes for both sensors to stabilize.
3. Verify In/Outdoor Humidity. Verify the indoor and outdoor humidity match
closely with the console and sensors in the same location (about 5 to 10′ (1.5
to 3 meters) apart). The sensors should be within 10% (the accuracy is ± 5%).
Allow about 30 minutes for both sensors to stabilize.
3.6 Sensors Installing Precaution
3.6.1 Test the Sensors Before Installation
Recommend to operate and test the weather station for one week before
installing it in the permanent location. In this period, you can check out all
of the functions, ensure proper operation, and familiarize with the
professional weather station and calibration procedures. This will also allow
you to test the wireless range of the weather station.
3.6.2 Site Survey Before Installation
Do a site survey before installing the weather station. Take the following
points into Consider:
1. Avoid radiant heat transfer from buildings and structures. In general,
install the sensor array at least 5ft (1.5m) from any building, structure,
ground, or roof top.
14
2. Avoid wind 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 20ft (6m) tall, install 4 x (20 6)’ = 56ft (17m)
away. Use common sense. If the weather station is installed next to a tall
building, the wind will not be accurate.
3. Wireless Range. The radio communication between display console and
transmitter in an open field can reach a distance of up to 330ft (100m),
assume there are no interfering obstacles such as buildings, trees, vehicles,
high voltage lines. Wireless radio signals will not penetrate metal buildings.
Most wireless applications will only reach up to100ft (30m) due to building
obstructions, walls and interference.
4. 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 display console or mounting locations.
3.6.3 Best Practices for Wireless Communication
Wireless communication is susceptible to other interference, such as distance,
walls and metal barriers. We recommend the following best and useful 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 433 MHz devices and
communication is intermittent, try turning off these other devices for
troubleshooting purposes. You may need to relocate the wireless transmitters
or receivers to avoid intermittent communication.
15
3. Line of Sight Rating. This device is rated at 300ft line of sight (no
interference, barriers or walls) but typically you will get 100ft 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. The following is a table of
reception loss vs. the transmission medium. Each “wall”or obstruction
decreases the transmission range by the factor shown below.
Medium
Glass (untreated) Plastics Wood Brick Concrete Metal
RF Signal Strength Reduction 5-15% 10-15% 10-40% 10-40% 40-80% 90-100%

4.7 Sensors Calibration Mode
Note: The calibrated value can only be adjusted on the display console.The outdoor remote sensor(s) always displays the un-calibrated or measured value.
Note: The measured humidity range is between 10% and 99%. Humidity cannot be accurately measured outside of this
28
range. Thus, the humidity cannot be calibrated below 10% or above 99%.
The purpose of calibration is to fine tune or correct for any sensor error
associated with the devices margin of error. The measurement can be adjusted
from the console to calibrate to a known source.
Calibration is only useful if you have a known calibrated source you can
compare it against, and is optional. This section discusses practices,
procedures and sources for sensor calibration to reduce manufacturing and
degradation errors. Do not compare your readings obtained from sources such as
the internet, radio, television or newspapers. They are in a different
location and typically update once per hour.
The purpose of the weather station is to measure conditions of your
surroundings, which vary significantly from location to location.
4.7.1 Temperature Calibration Mode
In normal mode, press and hold the SET and CHANNEL/+ keys at the same time for
five seconds to enter the temp calibration mode. The indoor temperature will
begin flashing.
Press the CHANNEL/+ key or MAX/MIN/- key to increase or decrease the
temperature reading (in increments of 0.1). Press and hold the CHANNEL/+ key
or MAX/MIN/- key for three seconds to increase or decrease rapidly.
29
Press the ALARM key to reset current value.
Press the SET key switch to sensor Temperature(CH1 to 8).
To exit the temperature calibration mode at any time, press the SNOOZE/LIGHT
button or SET key.
4.7.2 Humidity Calibration Mode
In normal mode, press and hold the SET and MAX/MIN/- keys at the same time for
five seconds to enter into the humidity calibration mode. The indoor humidity
will begin flashing.
Press the CHANNEL/+ key or MAX/MIN/- key to increase or decrease the humidity
reading (in increments of 1%). Press and hold the CHANNEL/+ key or MAX/MIN/-
key for three seconds to increase or decrease rapidly.
Press the ALARM key to reset current value.
Press the SET key switch to sensor humidity(CH1 to 8).
To exit the humidity calibration mode at any time, press the SNOOZE/LIGHT
button or SET key.
Note: The Humidity is a difficult parameter to measure accurately and drifts
over time. The calibration feature allows you to zero out this error. To
calibrate humidity, you will need an accurate source, such as a sling
psychrometer or Humidipaks One Step Calibration kit.
30
4.7.3 Wind Speed Calibration Mode
In normal mode, press and hold the SET and ALARM keys at the same time for
five seconds to enter the wind mode. The letter “CAL” will appear at the
screen. The wind speed value will flash (the default is 1.00).
Press the CHANNEL/+ key or MAX/MIN/- key to adjust the wind speed calibration
factor from 0.75 to 1.25, where:
Calibrated Wind Speed = Calibration factor x Measured Wind Speed
Press and hold the CHANNEL/+ or MAX/MIN/- key for three seconds to increase or
decrease rapidly.
Press the ALARM key to reset current value.
To exit the wind speed calibration mode at any time, press the SNOOZE/LIGHT
button or SET key.
Note: The wind gust is also affected by the wind speed calibration factor.
Discussion: Wind speed and wind gust are adversely affected by installation
constraints. The rule of thumb is to install the weather station four times
the distance of the height of the tallest obstruction (for example, a 6m(20ft)
house would require an installation 24m(80ft) away).
31
In many instances, due to trees and other obstructions, this is not possible.
The wind speed calibration allows you to correct for these obstructions. In
addition to installation challenges, wind speed bearings (any moving part)
wears over time. To correct for wear, the correction value can be increased
until the wind cups must be replaced. Without a calibrated source, wind speed
is a difficult parameter to measure. We recommend using a calibrated wind
meter and constant, high speed fan.
4.8 Factory Default Reset
To reset the display console to factory default, press the MAX/MIN/- key while
plugging in power adaptor at the same time ( Take out batteries before
starting the reset operation ).

If the sensor assembly is too close (less than 1.5m/5ft), move the sensor assembly away from the display console.
Make sure the remote sensor LCD display is working and the transmitter light
is flashing once per 60 seconds.
34
Install a fresh set of batteries in the remote sensor. For cold weather environments, install lithium batteries.
Make sure the remote sensors are not transmitting through solid metal (acts as an RF shield), or earth barrier (down a hill).
Move the display console around electrical noise generating devices, such as computers, TVs and other wireless transmitters or receivers.
Move the remote sensor to a higher location. Move the remote sensor to a closer location.
Indoor and Outdoor Temperature do not agree
Allow up to one hour for the sensors to stabilize due to signal filtering. The indoor and outdoor temperature sensors should agree within 2°C/4°F) (the sensor accuracy is ± 1°C/2°F).
Indoor and Outdoor Humidity do not agree
Use the calibration feature to match the indoor and outdoor temperature to a known source. Allow up to one hour for the sensors to stabilize due to signal filtering. The indoor and outdoor humidity sensors
