Replace the battery door, and unfold out the desk stand to
place the console in the upright position.
Note: The battery is a back-up of weather station console,
saving console settings when powered off from adaptor
3.4.3 Connect Sensor with Display Console
Once the display console is powered up, it will automatically
scan all the nearby Integrated Outdoor sensors.
Note: Do not press any button until all the remote sensors
report in the display screen, otherwise the display console will
terminate to connect with remote sensors.
Note: While in the search mode, the remote search icon
will be constantly displayed until all the measured values
received. The console will automatically switch to the normal
mode from which all further settings can be performed.
When connected with the Integrated Outdoor Sensor, the
measured value (Indoor temperature,humidity,pressure,moon
phase,time,wind speed,wind gust,wind direction,rain,outdoor
temperature and humidity) will show up on the display console.
Note: Make sure that the distance between weather station
sensors and display console should be within 10ft (3m) to 100ft
(30m). If the weather station sensors is too close or too far
away, it may not receive a proper signal.
3.5 Sensor Operation Verification

6
The following steps verify proper operation of the sensors prior
to install the sensor array.
1. Verify proper operation of the rain gauge. Tip the
Integrated outdoor sensor back and forth several times. You
will heard a “ticking” sound within the rain gauge. Verify the rain
reading on the display console is not reading 0.00. Each
“ticking” represents 0.1 inch of rainfall.
2. Verify proper operating of the wind speed. Rotate the
wind cups manually or with a constant speed fan. Verify the
wind speed is not reading 0.0.
3. Verify proper operation of in/outdoor temperature.
Verify the indoor and outdoor temperature match closely with
the console and sensor array 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.
4. Verify proper operation of in/outdoor humidity. Verify
the indoor and outdoor humidity match closely with the console
and sensor array 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.

9. Optional 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
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

17
internet, radio, television or newspapers. They are in a different
location and typically update once per hour.
The purpose of your weather station is to measure conditions
of your surroundings, which vary significantly from location to
location.
The profession weather station supports up to eight remote
thermo-hygrometer sensors. Each of the eight sensors can be
calibrated.
9.1 Calibration of Temperature 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.
Press the ALARM key to reset current value.
Press the SET key switch to outdoor Temperature.
To exit the temperature calibration mode at any time, press the
SNOOZE/LIGHT button of the display console. If no operation
is performed, the calibration mode will timeout in 30 seconds.
9.2 Calibration of Humidity Mode

18
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 outdoor humidity.
To exit the humidity calibration mode at any time, press the
SNOOZE/LIGHT button on the top of the display console. If no
operation is performed, the calibration mode will timeout in 30
seconds.
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.
9.3 Calibration of Sensors Mode
In normal mode, press and hold the SET and ALARM keys at
the same time for five seconds to enter the pressure, wind gust,
rainfall calibration mode. The letter “CAL” will appear at the
bottom of the screen.

19
Press the SET key to skip over a parameter to the next.
Absolute Pressure Calibration
In the calibration mode, the “ABS” symbol will display at the
pressure section, the absolute pressure value will flash. (The
default value is 0.00 inHg)
Press the CHANNEL/+ key or MAX/MIN/- key to increase or
decrease the absolute pressure value (in increments of 0.01
inHg).
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.
Example: The calibrated pressure sources measure 28.37
inHg. The display console pressure reads 28.75 inHg.
Offset = 28.37 - 28.75 = - 0.38 inHg
Relative Pressure Calibration
In the calibration mode, press the SET key once, the “REL”
symbol will display at the pressure section, the relative
pressure value will flash. (The default value is 0.00 inHg)
Press the CHANNEL/+ key or MAX/MIN/- key to increase or
decrease the relative pressure value (in increments of 0.01
inHg).
Press and hold the CHANNEL/+ or MAX/MIN/- key for three
seconds to increase or decrease rapidly.

20
Press the ALARM key to reset current value.
Example: The calibrated pressure sources measure 25.00
inHg. The display console pressure reads 24.85 inHg.
Offset = 25.00 - 24.85 = 0.15 inHg
Note: 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 the 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 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 (1013.2hpa).
This is the average sea-level pressure around the world.
Relative pressure measurements greater than 29.92 inHg
(1013.2hpa) 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 from you (the internet is the best
source for real-time barometer conditions, such as the website
