8. HUMIDITY AND AIR PRESSURE INFORMATION
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
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.
