The tendency indicators arrow is located beside the air pres-

sure value to show the air pressure tendency and provide a fore-

cast of the weather to be expected by the decreasing or increa-

sing 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 pressu-

re without change within 30minutes. The base unit measure the air pressure per

10 minutes. If the air pressure continuous increasing 3 times

the arrow will be upward, if the air pressure continuous decrea-

sing 3 times the arrow will be downward, otherwise the tenden-

cy arrow will not show up.

The pressure threshold can be set to suit the user’s require-

ment for weather forecasting from 2-4 hPa (default 2 hPa).

There is pressure sensitivity icon on the top left corner of LCD to indicate the pres-

sure 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 pres-

sure 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.
