V alue to show the air pressure 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 ten-

dency arrow will not show up.

The pressure threshold can be set to suit the user’s requirement for weather forecasting from

2-4 hPa (default 2 hPa). There is pressure sensitivity icon on the top left corner of LCD to indica-

te 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 befo-

re the weather station will register this as a change in weather.
