3. 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 remote temperature and humidity will update on the display within a
few minutes on the appropriate channel.

Version 1.1 ©Copyright 2014, Ambient LLC. All Rights Reserved. Page 6
While in the search mode, the remote search icon will be constantly displayed.
If you have more than once remote sensor (up to eight remotes are supported), the
display will automatically toggle between sensors until all sensors have reported in.
Do not touch any buttons until the remote sensor has reported in, or the radio search icon
is no longer on, otherwise the remote sensor search mode will be terminated. When
the remote sensor temperature and humidity 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 10.
Note: The power adapter is intended to be correctly oriented in a vertical or floor
mounted position. The prongs are not designed to hold the plug in place if it is plugged into a
ceiling, under-the-table or cabinet outlet.

2.4.2 Sensor Operation Verification
Verify the indoor and outdoor humidity match closely with the console and sensor array in the
same location (about 5’ to 10’ apart). The sensors should be within 10% (the accuracy is ± 5%).
Allow about 30 minutes for both sensors to stabilize. The humidity can be adjusted or calibrated
later to match each other a known source.
Verify the indoor and outdoor temperature match closely with the console and sensor array in the
same location (about 5’ to 10’ apart). The sensors should be within 3°F (the accuracy is ± 2°F).
Allow about 30 minutes for both sensors to stabilize. The temperature can be adjusted or
calibrated later to match each other or a known source.
3Remote Sensor Installation
It is recommended you mount the remote sensor outside in a shaded area. A north facing wall is
preferred because it is in the shade most of the day. Direct sunlight and radiant heat sources will
result in inaccurate temperature readings. Although the sensor is water resistant, it is best to mount
in a well protected area, such as under an eve. Use a screw or nail (not included) to affix the
remote sensor to the wall, as shown in Figure 7.

Version 1.1 ©Copyright 2014, Ambient LLC. All Rights Reserved. Page 15
5.9 Adjustment or Calibration
Note: The calibrated value can only be adjusted on the console. The 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 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 WS-110 supports up to eight remote sensors. Each of the eight sensors can be calibrated.
If you own more than one remote sensor, press the CHANNEL/+ button first to display the
specific channel you wish to calibrate.
5.9.1 Temperature Calibration
In normal mode, press and hold the SET and CHANNEL/+ keys at the same time for five
seconds to enter the temperature calibration mode. The indoor temperature will begin flashing.
Press the [+] or [-] key to increase or decrease the temperature reading (in increments of 0.1).
Press and hold the [+] or [-] key for three seconds to increase or decrease rapidly.
Press the ALARM key to reset current value.
Press the SET key switch to next channel (1through 8). If no operation is performed, the
calibration mode will timeout in 30 seconds.
5.9.2 Setting Calibrated Humidity
In normal mode, press and hold the SET and HISTORY/- keys at the same time for five seconds
to enter the humidity calibration mode. The indoor humidity will begin flashing.

Version 1.1 ©Copyright 2014, Ambient LLC. All Rights Reserved. Page 16
Press the [+] or [-] key to increase or decrease the humidity reading (in increments of 1%). Press
and hold the [+] or [-] key for three seconds to increase or decrease rapidly.
Press the ALARM key to reset current value.
Press the SET key switch to next channel (1through 8). If no operation is performed, the
calibration mode will timeout in 30 seconds.
Note: 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.
5.9.3 Setting Calibrated Barometric Pressure
In normal mode, press and hold the SET and ALARM keys at the same time for five seconds to
enter the barometric pressure calibration mode. The absolute relative pressure (ABS) will begin
flashing.
1. Absolute Pressure. Press the [+] or [-] key to increase or decrease the absolute pressure
reading (in increments of 0.01). Press and hold the [+] or [-] key for three seconds to increase
or decrease rapidly.
Press the ALARM key to reset current value.
Press the SET key to adjust the relative pressure.
2. Relative Pressure. Press the [+] or [-] key to increase or decrease the relative pressure
reading (in increments of 0.01). Press and hold the [+] or [-] key for three seconds to increase
or decrease rapidly.
Press the ALARM key to reset current value.
If no operation is performed, the calibration mode will timeout in 30 seconds.
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 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

Version 1.1 ©Copyright 2014, Ambient LLC. All Rights Reserved. Page 17
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.

12. Outdoor 1 (channel 1) humidity low alarm
Note: To prevent repetitive alarming of temperature, there is a 0.9 °F tolerance band. For
example, if you set the high alarm to 80.0 °F and silence the alarm, the alarm icon will continue to
flash until the temperature falls below 79.1 °F, at which point, the alarm will reset and must
increase above 80.0 °F to activate again.
Note: To prevent repetitive alarming of humidity, there is a 4% tolerance band. For example,
if you set the high alarm to 60% and silence the alarm, the alarm icon will continue to flash until
the humidity falls below 56%, at which point, the alarm will reset and must increase above 60% to
activate again.
6.4 Alarm and Command Key Beeper ON/OFF Mode
The beeper can be silenced for both alarms and key strokes.
In normal mode, press and hold the ALARM key for five seconds to toggle the beeper on or off
(depending on the current setting).
The BUZZON (beeper on) or BUZZOFF (beeper off) icon will appear in the time area for three
seconds. Press and hold the ALARM button again for five seconds to toggle the BUZZON or
BUZZOFF command.

7.2 Personalizing Color Ranges
You can customize your background color ranges to suit your location, or personal preferences.
For example, if you live in Alaska, your definition of hot and cold may be very different if you
live in Arizona.
Likewise, if you track your indoor comfort level, your comfort range may be very different than
someone else.
Example 1: I live in Arizona, and the temperature ranges from 10 °F to 120 °F.
Color Increment = (HI-LOW)/11 = (120 –10)/11 = 10 °F.
Yellow = 7 x 10 + 10 = 80 °F, which is comfortable forArizona.
Example 2: I live in Alaska, and the temperature ranges from -20°F to 90°F.
Color Increments = (HI-LOW)/11 = (90 –(-20))/11 = 10 °F.
Yellow = 7 x 10 - 20 = 50 °F, which is comfortable forAlaska.

8. Glossary of Terms
Term
Definition
Accuracy
Accuracy is defined as the ability of a measurement to match the actual
value of the quantity being measured.
Hygrometer
A hygrometer is a device that measures relative humidity. Relative
humidity is a term used to describe the amount or percentage of water
vapor that exists in air.
Range
Range is defined as the amount or extent a value can be measured.
Absolute Barometric
Pressure
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.
Relative Barometric
Pressure
Measured barometric pressure relative to your location or ambient
conditions.
HectoPascals (hPa)
Pressure units in SI (international system) units of measurement. Same
as millibars (1 hPa = 1 mbar)
Inches of Mercury (inHg)
Pressure in Imperial units of measure.
1 inch of mercury = 33.86 millibars
