8. HUMIDITY AND AIR PRESSURE INFORMATION
10
8.1 Relative Humidity Trend Display
After you insert the batteries, the weather station measures the current relative humidity.
The trend display shows a neutral relative humidity course . The further course of the
trend display is determined as follows:
●
If, after an hour, the relative humidity is more than 5% higher than the value measured
first, then a positive course is displayed .
●
If, after an hour, the relaive humidity is more than 5% lower than the value measured
first, then a negative course is displayed .
●
If the relative humidity does not change within an hour, the the upward or downward
pointing arrow becomes a horizontal arrow. The measured relative humidity is then
taken as the neutral value from which further prognoses are made.
8.2 Maximum/Minimum Relative Humidity
●
The Weather Station will automatically show the daily Max and Min Relative Humidity
once it starts receiving readings. These will reset at 0.00 automatically.
8.3 Barometric Pressure Display
●
The current barometric pressure is automatically shown on the Weather Station once it
starts receiving readings.
●
The barometric pressure can be displayed in either mb/hPa, inHg or mmHg. The units
can be slected when by following in the manual time setup on page 7.
●
If the barometric pressure reading is below the minimum range, then
LLLL
will be
displayed. If the barometric pressure reading is above the maximum range, then
HHHH
will be displayed.
8.4 Relative Barometric Pressure History
The relative barometric pressure history can be displayed to view the air pressure changes
over the last 0-12 hours.
Press the
+
button repeatedly to display the recorded barometric pressure during the last
0-12 hours. The numeric recorded air pressure will be displayed according to the hour.
●
0HR = Present barometric pressure.
●
-1HR = Barometric pressure an hour earlier.
●
-2HR = Barometric pressure an two hours earlier, etc.
Note: After 20 seconds without pressing any button the clock will switch back to the current
barometric pressure reading.
