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 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.
TOGGLING AND RESETTING THE OUTDOOR DATA
1.
To toggle between the outdoor current, MAX/MIN temperature and humidity data and the
times (for temperature data only) they were recorded press the OUT/+ key:
Once to show the MAX outdoor temperature and humidity data with the recorded time and
date.
Twice to show the MIN outdoor temperature and humidity data with the recorded time and
date.
Three times to return to the current displayed values.
2.
Once the MIN or MAX data is displayed, press and hold the SET key for 3 seconds to reset
the respective MIN or MAX record to current temperature and humidity data, and current
time, date display.
Note: The MIN or MAX data needs to be reset individually.
TO VIEW THE MIN/MAX DATA FROM DIFFERENT TRANSMITTERS
When more than 1 transmitter used:
