Weather Tendency Indicator - Dostmann 35.1045.IT Manuel D'instructions

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 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.
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 fourth LCD section shows the outdoor temperature and humidity, the reception indicator,
the transmitter identification number and the MIN/MAX outdoor data.
