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 air-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
indicators (located on the left and right sides of the weather icons). When
the indicator points upwards, it means that the air-pressure is increasing
and the weather is expected to improve, but when indicator 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 third section of the LCD also shows the relative air pressure value
and the air pressure history.
The bar chart indicates the air pressure history trend over the last 12
hours in 5 steps, 0h, -3h, -6h, -9h, and -12h. The “0h” represents the
current full hour air pressure recording. The columns represent the “hPa”
(0, ±2, ±4) at specific time. The “0” in the middle of this scale is equal to
the current pressure and each change (±2, ±4) 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 example, it should not be moved from the
ground to the second floor of the house. Should the unit be moved to a
new location, discard readings for the next 12-24 hours.
OUTDOOR TEMPERATURE
The fourth LCD section shows the outdoor temperature, the reception
indicator, the transmitter identification number and the MIN/MAX outdoor
data.
