2.4 Display Console Set Up
Note: To avoid permanent damage, please take note of the battery polarity before inserting the
batteries.
Move the remote thermo-hygrometer at least 10’ away from the display console (if the sensor is too
close, it may not be received by the display console).
Remove the battery door on the back of the display. Insert three AA (alkaline or lithium, avoid
rechargeable) batteries in the back of the display console. Looking at the back of the unit (left to right),
the polarity is (+) (-) for the top battery, (-) (+) for the middle battery and (+) (-) for the bottom battery.
The display will beep once and all of the LCD segments will light up for a few seconds to verify all
segments are operating properly.
Replace the battery door, and fold out the desk stand and place the console in the upright position.
The console will instantly display indoor temperature, humidity, barometer, tendency, date and time.
The outdoor temperature and humidity will update on the display within a few minutes. Do not touch
any buttons until the remote sensor reports in, otherwise the remote sensor search mode will be
terminated. When the remote sensor data has been received, the console will automatically switch to
the normal mode, and all further settings can be performed.
If the remote does not update, please reference the troubleshooting guide in Section 7.
2.4.1 Radio Controlled Clock (RCC)
The RCC is received by the remote sensor and transmitted to the main console to improve reception.
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 10 minutes), no weather data will be transmitted to avoid interference.
If the signal reception is not successful within 1 minute, the signal search will be cancelled and will
automatically resume every two hours until the signal is successfully captured. The regular RF link
will resume once RCC reception routine is finished. In some locations, it may take a couple of days to
receive the radio control signal.

4.2.1 Setting Barometric Pressure
Note: This is a continuation of the previous section. To enter this mode, you must start at the
beginning of this section.
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 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.
To change the relative pressure in the SET mode, press the + key or MIN/MAX key to increase or
decrease the relative pressure setting to match the official reporting station.
4.2.2 Setting Calibrated Humidity
Note: This is a continuation of the previous section. To enter this mode, you must start at the
beginning of this section.
The display console allows you to calibrate both the indoor and outdoor humidity. 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, available from Ambient Weather, which uses a
salt bath.
To calibrate indoor humidity, in the Set Mode with indoor humidity flashing, press the + key or

MIN/MAX key to increase or decrease the humidity setting (in increments of 1%) to match the
calibrated or known humidity source. To return the indoor humidity to the measured value, press and
hold the SET key for 3 seconds and the humidity will return to the uncalibrated value.
Note: The remote (outdoor) thermo-hygrometer will always display the measured humidity level
and not the calibrated humidity level. Only the console will show the calibrated value.
Note: The dew point calculation is based on the calibrated humidity level.

4.5 Other Console Features
The following section describes additional console features.
4.5.1 Weather Forecasting
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).
The weather forecast is an estimation or generalization of weather changes in the next 24 to 48 hours,
and varies from location to location. The tendency is simply a tool for projecting weather conditions
and is never to be relied upon as an accurate method to predict the weather. ***
4.5.2 Weather Icons
Sunny
Partly Cloudy
Cloudy
Rainy
The four weather icons are Sunny, Partly Cloudy, Cloudy and Rainy. There are also two weather
tendency indicators to show the air pressure tendency between the weather icons.
4.5.3 Weather tendency indicator
The weather tendency arrow is located between the weather icons to show the air pressure tendency
and provide a forecast based on increasing or decreasing air pressure.
The arrow pointing to the right indicates that the air pressure is increasing and the weather is expected
to improve. The arrow pointing the left indicates that the air pressure is decreasing and the weather is
expected to deteriorate.
The weather tendency is based on the pressure change since last six hours. If the weather is changing,
Version 1.0

Page 11
the weather tendency indicator (animated arrows) will flash for three hours, indicating the weather is
expected to change. If the weather conditions become stable and no new weather change conditions
are met, then the arrows will be fixed.
Example 1: Pressure is decreasing, weather is deteriorating.
Example 2: Pressure is increasing, weather is improving.
4.5.4 Storm threshold indicator
The storm threshold (the negative rate of pressure change signifying a storm is expected) can be
adjusted by the user from level 3 to level 9 (the default level 4 mbar/hour).
When negative rate of change of pressure is exceeded for 3 hours, the storm warning indicator will be
activated, and the clouds with rain icon and tendency arrows will flash for 3 hours indicating the storm
warning feature has been activated.
4.5.5 Pressure threshold setting
The pressure threshold (the negative or positive rate of change of pressure signifying a change in the
weather) can be adjusted by the user from level 2 to level 4 (default level 2 mbar/hour).
The lower the level pressure threshold setting, the higher sensitivity for weather forecast changes.
Locations that experience frequent changes in air pressure require a higher setting compared to
locations where the air pressure is typically stagnant.

Definition
Relative barometric pressure, 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.
Accuracy is defined as the ability of a measurement to match the actual
value of the quantity being measured.

following radiation shield if this is not possible:
http://www.ambientweather.com/amwesrpatean.html
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).
Allow up to one hour for the sensors to stabilize due to
signal filtering. The indoor and outdoor humidity sensors
should agree within 10 % (the sensor accuracy is ± 5 %).
Use the calibration feature to match the indoor and
outdoor humidity to a known source.
The console displays the calibrated humidity. The remote
displays the measured humidity only. Refer to 4.2.2 to
set and reset the humidity calibration.
You may be viewing the absolute pressure, not the
relative pressure.
Select the relative pressure. Make sure you properly
calibrate the sensor to an official local weather station.

Version 1.0
The barometer is only accurate to ± 0.08 inHg within the
following absolute pressure range: 27.13 to 32.50 inHg,
which corresponds to an altitude of -2,200 to 2,700 feet.
At higher altitudes, expect some non-linearity or error.
The weather station console must run for several days to
trend barometric pressure.
The weather forecast is an estimation or generalization of
weather changes in the next 24 to 48 hours, and varies
from location to location. The tendency is simply a tool
for projecting weather conditions and is never to be
relied upon as an accurate method to predict the weather.
Replace console batteries with a fresh set of batteries.
