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 fourth section of the LCD also shows the relative air pressure value and the
air pressure history.
Air pressure over the last 24 hours
The bar chart indicates the air pressure history trend over the last 24 hours in 7
steps, 0h, -3h, -6h, -9h, -12h, -18h, and -24h. The "0h" represents the current full
hour air pressure recording. The columns represent the "hPa" (0, ±2, ±4, ±6) at
specific time. The "0" in the middle of this scale is equal to the current pressure
and each change (±2, ±4, ±6) 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/HUMIDITY DATA
The last LCD section shows the outdoor temperature and humidity, the reception
indicator, the transmitter identification number and the MIN/MAX outdoor data.
