The tendency indicators arrow is located beside the air pressure value to show the air pres-
sure tendency and provide a forecast of the weather to be expected by the decreasing or
increasing air pressure. The upward arrow means that the air pressure is increasing and the
weather is expected to become better. The downward arrow means that the air pressure is
decreasing and the weather is expected to become worse. The tendency indicator arrow will not show up while
the pressure without change within 30minutes. The base unit measure the air pressure per 10minutes. If the air
pressure continuous increasing 3 times the arrow will be upward, if the air pressure continuous decreasing 3 times
the arrow will be downward, otherwise the tendency arrow will not show up.
The pressure threshold can be set to suit the user’s requirement for weather forecasting from 2-
4hPa (default 2hPa). There is pressure sensitivity icon on the top left corner of LCD to indicate the
pressure threshold by number of dots. For areas that experience frequent changes in air pressure
requires a higher setting compared to an area where the air pressure is stagnant. For example if
4hPa is selected, then there must be a fall or rise in air pressure of at least 4hPa before the weather station will
register this as a change in weather.
The storm waning pressure threshold can be set to suit the user’s requirement from 3-5hPa (default
4hPa).When there is a fall over pressure threshold within 3 hours, the storm forecasting will be activated, the storm
icon will flash indicating the storm warning feature has been activated.
When outdoor temperature between -3 to 1 degree ice alert icon would be indicated.
If you have purchased additional remote sensors, ice alert is base on the tempertature of Channel
1 sensor.
