Weather Forecast Icons
Weather tendency arrows are located between the weather icons to show the atmospheric pressure tendency
and to provide the weather to be expected by decreasing or increasing the atmospheric pressure.
The rightward arrows indicate an increase of the atmospheric pressure and a weather
improvement. The leftward arrows indicate a decrease of the atmospheric pressure
and a weather worsening.
The change of the icons is in accord to the relationship between the current relative
pressure and the pressure change of the last six hours. If the weather is changing, the
weather tendency arrows will be flashing for three hours indicating a weather change
is happening. After that, the arrows will stop flashing when conditions have become
stable and no weather changes are expected.
d.
Storm Warning Icon
The storm threshold can be set to suit your requirement for storm forecasting from
3 ~ 9 hPa (default 4 hPa). When there is a fall over the pressure threshold within 3
hours, the storm forecasting will be activated, and the rainy icon and the arrows will
flash for 3 hours indicating the storm warning feature has been activated.
Note to pressure sensitivity setting for weather forecasting
The atmospheric pressure threshold can be set to suit your requirement for weather forecasting from 2 ~ 4 hPa
(default 2 hPa). Areas that experience frequent pressure changes require a higher setting compared to an area
where the atmospheric pressure is stagnant.
5. Programming Your Weather Station
a.
Quick Display Mode
•
In normal display mode, press SET.
o
Outdoor temperature / Dew point / Wind chill: press MIN / MAX or + to switch between the outdoor
temperature, the dew point and wind chill.
o
Absolute pressure / Relative pressure: press MIN / MAX or + to switch between the absolute and the
relative pressure.
o
Wind speed / gust speed: press MIN / MAX or + to switch between the wind speed and the gust speed.
o
1h / 24h / week / month / total rainfall: press MIN / MAX or + to switch between the rainfall quantities.
Hold SET pressed to reset the value.
•
Press SET to confirm the settings and to move to the next setting level. Press SET to scroll through the
display mode and to return to the normal display mode.
b.
Setting Modes
•
In normal display mode, hold SET pressed for 3 seconds.
•
Press SET to select a setting in the following sequence: Time zone format – 12 / 24h format – Manual time
setting (h / m) – Calendar setting (Y / M / D) – Temperature scale unit (°C or °F) – Atmospheric pressure
unit (hPa or inHg) – Relative pressure setting from 919.0 hPa ~ 1080.0 hPa (default 1013.5 hPa) –
Atmospheric pressure threshold setting (default 2 hPa) – Storm threshold setting (default 4 hPa) – Wind
and gust speed (km/h, mph, m/s, knots, Bf) – Rainfall (mm or inch).
•
Press + or MIN / MAX to modify the settings. Hold + pressed for 3 seconds to modify the setting rapidly.
•
