Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting feature
is estimated to have an accuracy level of about 75% due to the varying areas the weather station has been
designed for use. In areas that experience sudden changes in weather (for example from sunny to rain), the
weather station will be more accurate compared to use in areas where the weather is stagnant most of the
time (for example mostly sunny).
If the weather station is moved to another location significantly higher or lower than its initial standing point
(for example from the ground floor to the upper floors of a house), discard the weather forecast for the next
12-24 hours. By doing this, the weather station will not mistake the new location as being a possible change
in atmospheric pressure when really it is due to the slight change of altitude.
WEATHER TENDENCY INDICATOR
Working together with the weather icons is the weather tendency indicator (located on the left of the weather
icons). When the arrow points upwards, it means that the air pressure is increasing and the weather is
expected to improve, but when arrow points downwards, the air pressure is dropping and the weather is
expected to become worse.
Taking this into account, one can see how the weather has changed and is expected to change. For
example, if the indicator is pointing downwards together with cloud and sun icons, then the last noticeable
change in the weather was when it was sunny (the sun icon only). Therefore, the next change in the weather
will be cloud with rain icons since the indicator is pointing downwards.
Note:
Once the weather tendency indicator has registered a change in air pressure, it will remain permanently
visualized on the LCD.
AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC PRESSURE
TREND)
The right side of the second section of the LCD shows the air pressure history bar graph.
The bar graph indicates the air pressure history trend over the last 12 hours in 5 intervals: 0h, -3h, -6h, -9h
and -12h. The "0h" represents the current full hour air pressure recording. The columns represent the "hPa"
(0, ±1, ±3, ±5) at specific time. The "0" in the middle of this scale is equal to the current pressure and each
change (±1, ±3, ±5) represents how high or low in "hPa" the past pressure was compared to the current
pressure.
If the bars are rising it means that the weather is getting better due to the increase of air pressure. If the bars
go down, it means the air pressure has dropped and the weather is expected to get worse from the present
time "0h".
Note:
For accurate barometric pressure trends, the weather station should operate at the same altitude for
recordings (i.e. it should not be moved from the ground to the second floor of the house). When the unit is
moved to a new location, discard readings for the next 12 hours.
