3.2 Thermo-Hygrometer Sensor Set Up
Note: To avoid operating problems, please take note of battery polarity
before/when inserting any Alkaline Batteries (permanent damaged could be
introduced by inserting the battery in wrong direction). Do not use
rechargeable batteries. We recommend fresh alkaline batteries for outdoor
temperature range between -20°Cand 60°C and fresh lithium batteries for
outdoor temperature range between -40°C and 60°C.
1. Move the transmitter(s) about 2 to 3m away from the display console
(if the transmitters are too close, they may not be received by the
display console). With multiple transmitters, make sure all transmitters
are powered up and displaying different channels on the display.
2. Remove the battery door on the back of the thermo-hygrometer sensor
by sliding down the battery door.

9. Close the battery door.
10. Repeat for the additional remote sensor, verifying each remote is on a
different channel.
3.3 Sensor Operation Verification
Verify the humidity sensors match closely with all of the sensors in the same
location (about 2 to 3m apart). The sensors should agree within 10% (the
accuracy is ± 5%). Allow about 30 minutes for all sensors to stabilize. The
humidity can be adjusted or calibrated later to match each other a known
source.

Color Screen Multi-channel Weather Station User Manual

Verify the temperature sensors match closely with all of the sensors in the
same location (about 2 to 3m apart). The sensors should be within 2°C (the
accuracy is ± 1°C). Allow about 30 minutes for all sensors to stabilize. The
temperature can be adjusted or calibrated later to match each other or a
known source.
3.4 Radio Controlled Clock (RCC)
After the remote sensor is powered up, the sensor will transmit weather
data for 30 seconds, and then the sensor will begin radio controlled clock
(RCC) reception. During the RCC time reception period (maximum 5
minutes), no weather data will be transmitted to avoid interference. Once
the radio controlled time is received the RCC signal received successfully,
the RCC reception icon will turn on in the outdoor sensor LCD display.
Then outdoor sensor sends the RCC signal to display console, Once the
radio controlled time is received, RCC reception icon will turn on in the
display console. (reference Figure 8).
If the signal reception is not successful within 3 minute, the signal search
will be cancelled and will automatically resume every six hours until the
signal is successfully captured. The regular RF link will resume once RCC
reception routine is finished. In some locations, RCC reception may take a
couple of days to receive the signal.
3.5 Remote Sensor Installation
Before mount the units, ensuring that the receiver can still pick up the signal
from transmitters. It is recommended to mount the sensors on a north facing
wall, in a shaded area. Direct sunlight and radiant heat sources will result in
inaccurate temperature readings. Although the sensors are water resistant,
it is best to mount in a well protected area, such as under an eve.
1. Use a screw or nail to affix the remote sensor to the wall, as shown in
Figure 6
2. Hang the remote sensor up on string, as shown in Figure 7.

4.3 Check Barometric Pressure
4.3.1 Barometric Pressure History
While in normal mode, press BARO./- to check the barometric pressure.
Press the BARO./- button to switch to past 12hr/24hr/48hr/72hr average
pressure. To exit the barometric pressure history mode, press the
SNOOZE/LIGHT key (on the top of the display console), or wait 30 seconds
for the timeout to take effect.
4.3.2 Relative Pressure Calaibration
You will want to calculate your barometric pressure to an official reporting
station in your area. Since barometric pressure does not drastically
change in a 50 mile radius (unless the weather is rapidly changing), this
method of calibration is acceptable.
To determine the relative pressure for your location, locate an official
reporting station near you (the internet is the best source for real time
barometer conditions, such as Weather.com or Wunderground.com), and
set your weather station to match the official reporting station.
4.3.3 Relative vs. Absolute Pressure
While in normal mode, Press and hold the BARO./- button for 2 seconds
you can switch between absolute (ABS) pressure and relative (REL)
pressure.
The display console displays two different pressures: absolute (measured)
and relative (corrected to sea-level).
To compare pressure conditions from one location to another,
meteorologists correct pressure to sea-level conditions. Because the air
pressure decreases as you rise in altitude, the sea-level corrected pressure
(the pressure your location would be at if located at sea-level) is generally
higher than your measured pressure.
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude

Color Screen Multi-channel Weather Station User Manual
14
of 1000 feet (305 m), but the relative pressure is 30.00 inHg (1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the
average sea-level pressure around the world. Relative pressure
measurements greater than 29.92 inHg (1013 mb) are considered high
pressure and relative pressure measurements less than 29.92 inHg are
considered low pressure.
To determine the relative pressure for your location, locate an official
reporting station near you (the internet is the best source for real time
barometer conditions, such as Weather.com or Wunderground.com), and
set your weather station to match the official reporting station.
4.4 Dew point
While in normal mode, Press the TEMP/+ key to view the Dew Point of
current channel in the outdoor temperature Segment. If key idle 30 seconds,
the display will return to normal mode.
To exit the Dew Point display mode, press the SNOOZE/LIGHT key (on the
top of the display console), or wait 30 seconds for the timeout to take effect.
4.5 ALARM Mode
While in normal mode, press the ALARM key to view the alarm time. The
alarm icon will be displayed in the time field.
4.5.1 Time ALARM

4.5.2 Low temperature ALARM
Low temperature ALARM is an ALARM happens when outdoor temperature
falls into (or goes up to) -3~2 c range. Once there is outdoor temperature of
any sensor falls into this temperature range, the low temperature alarm
would be triggered. The LO temperature icon will appear and flash
on the console. If the BEEP is switched on, a sound ALARM would be also
activated when Low temperature ALARM occurs.
4.5.3 Cancelling the ALARM
When time ALARM or Low temperature ALARM is triggered, press any key
to close the sound alarm. During time ALARM, press LIGHT/SNOOZE key
can enter snooze mode.
The Low temperature ALARM will reset automatically once the value has
fallen into the Low temperature ALARM range.
4.6 Calibration Mode
While in normal node, press and hold the SET/CH and BARO./- buttons 5
seconds to enter calibration mode(note: the SET mode will appear after
three seconds. Continue pressing the two keys until you see the CAL icon

appear in the upper right hand corner of the display).
The calibration sequence would be as below:
1. CH1 Outdoor temperature calibration.
2. CH1 Outdoor humidity calibration.
3. CH2 Outdoor temperature calibration.
4. CH2 Outdoor humidity calibration.
5. CH3 Outdoor temperature calibration.
6. CH3 Outdoor humidity calibration.
7. Indoor temperature calibration.
8. Indoor humidity calibration.
9. Absolute pressure calibration.
In calibration mode, press + and - buttons to adjust offset values, then press
SET/CH to confirm and proceed to next parameter. Press the ALARM
button to cancel offset values.
Example 1:
The calibrated temperature from a red spirit thermometer, or actual
temperature is 30.0 °C
The uncalibrated or measured temperature is 28.7 °C.
Offset = Calibrated Temperature – Uncalibrated Temperature = 30.0 – 28.7
= 1.3 °C.
Enter the temperature offset +1.3 °C.
Example 2:
The calibrated absolute pressure from a calibrated pressure sensor, or
actual absolute pressure is 28.61 inHg.
The uncalibrated or measured absolute pressure measured by the weather
station is 28.66 inHg.
Offset = 28.66 – 28.61 = -0.05 inHg
Enter the absolute pressure offset -0.05 inHg
Note: The absolute pressure offset will also affect the relative pressure.
To adjust the relative pressure, only (independent of the absolute
pressure), reference Section 5.1.

Color Screen Multi-channel Weather Station User Manual
17
Normally, you would not calibrate the absolute pressure because it is
difficult to obtain a calibrated source. The preferred method is to calculate
relative pressure to an official source near you, as described in Section
4.3.2.
During calibration mode, press LIGHT/SNOOZE to exit calibration mode.
Please note Offset values range as below:
Temperature offset calibrated (range +/-9F, default: 0 degrees).
Humidity offset calibrated (range +/-9%)
Pressure offset calibrated (range +/-10hpa)
4.7 MAX/MIN Mode
The Max/Min weather data are displayed on the bottom of each parameter
segment. Left one in red color is MAX record, right one in blue or yellow is
MIN record. All the MAX/MIN records are based on since last reset time
after turned on.
Max temperature Min temperature Max humidity Min humidity
All MAX/MIN records of all sensors can be cleared if you press and hold the
TEMP button for 2 seconds.
MAX/MIN records are cleared on 0:00 every day default. And below

4.8 Other Console Features
4.8.1 Color Weather Forecasting
This station learns. Please allow 30 days for barometric calibration. This will
ensure an accurate personal forecast for your location.
Six color forecast icons use changing atmospheric pressure to predict
weather conditions for the next 12-hours .
Note: The weather forecast or pressure tendency is based on the rate of
change of barometric pressure. In general, when the pressure increases,
the weather improves (sunny to partly cloudy) and when the pressure
decreases, the weather degrades (cloudy to rain).
