The ‘Sunny’ forecast covering night hours indicates clear weather.
HOW TO CHECK THE BAROMETRIC PRESSURE
The current and historical barometric pressure is shown on the atmospheric pressure window.
For monitoring the Sea Level barometric pressure reading at certain altitude, the user needs to
select the local altitude (-100 to 2500 meter or -330 to 8200 foot) for the altitude setting. The weather
station requires entry of elevation in meter and in foot separately. To determine your location
elevation, please either contact your local library, TV/radio weather forecaster, or via Internet.
1. To enter the altitude compensation setting mode, press and hold [HISTORY] button for 2 seconds
to switch from Barometric Pressure to Altitude adjust mode for 10 seconds and the meter icon
flashes.
2. During Altitude adjust mode, press [UNIT] button to toggle between meter and foot unit. Then
press [HISTORY] button to confirm.
3. Last altitude reading will flash, press [UNIT] button to increase the value by 10. Hold down the
button to have fast stepping. Press [HISTORY] button once to confirm and exit setting.
The atmospheric pressure can be displayed in mb/hPa, inHg. Press [UNIT] to select the pressure unit.
The weather station is equipped with barometer reading for 24hr history. If you want to check the
pressure history for a particular hour during the past 24 hours, press [HISTORY] button, each press on
the button will go back by an hour.
Note:
If the weather station was just installed with batteries and past data was not yet measured, it will
display ‘----‘.
The recorded barometric changes for the past 24 hours are displayed in a bar chart below the
barometric pressure window.
