1. In normal operating mode, press the BARO button to cycle through options for the barometer units
of measure in the following order: hPa > inHg > mmHg.
2. While in normal operating mode, press and hold the BARO button to switch between ABSOLUTE
and RELATIVE barometric pressure displays.
1. Obtain the atmospheric pressure data of the sea level (this is also the relative atmospheric
pressure data of your home area) through the local weather service, internet, or any similar
weather information source.
2. While in normal operating mode, press and hold the BARO button for two (2) seconds until the
ABSOLUTE or RELATIVE icon ashes.
3. Press the GRAPH/ or HISTORY/ buttons to switch to RELATIVE mode.
4. Press the BARO button again and the RELATIVE atmospheric pressure digit will start ashing.
5. Press the GRAPH/ or HISTORY/ buttons to adjust the value.
6. Press the BARO button one nal time to save and exit the setting mode.
1. Press and hold the RAIN button for two (2) seconds to enter unit setting mode.
2. Press the GRAPH/ or HISTORY/ buttons to toggle the units of measure for rainfall between
mm and in.
3. Press the RAIN button again to save and exit the setting mode.

The atmospheric pressure is the pressure at any location on Earth caused by the weight of the
column of air directly above that location. The average pressure gradually decreases as the altitude
increases. Meteorologists use barometers to measure atmospheric pressure. Since variation in
atmospheric pressure can be greatly aected by the weather, it is possible to forecast the weather
by measuring these changes in pressure.
The Rainfall section is located in the same area as the Barometric Pressure section of the LCD
display. It shows information regarding the rainfall and rain rate.
Press the RAIN button to toggle between:
1. HOURLY: total rainfall in the past hour
2. DAILY: total rainfall since midnight
3. WEEKLY: total rainfall for the current week
4. MONTHLY: total rainfall since the beginning of the current month
5. RATE: current rainfall rate in the past hour (updates every 24 seconds)
6. ACCUMULATION: total rainfall since the last reset (will show the record start date on the display
for ve seconds)
While in normal operating mode, press and hold the °C/°F button for two (2) seconds to reset the
ACCUMULATION rainfall record.
While in normal operating mode, press the GRAPH/ button to cycle between the dierent types of
graphs:
NOTE:
• When you change the RELATIVE atmospheric pressure value, the weather indicators will change
along with it.
• The RELATIVE atmospheric pressure is based on the sea-level pressure data you enter, but will
change with the absolute atmospheric pressure after an hour of operating the clock.
NOTE:
• To ensure precise data, please reset the ACCUMULATION rainfall record whenever you move and
reinstall your wireless weather sensor to a dierent location.
