Air Pressure History (Electronic Barometer With Barometric Pressure Trend) - La Crosse Technology Weather Station Instruction Manual

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 12 hours in 5 steps, 0h, -3h, -6h, -9h, and -12h. The
"0h" represents the current full hour air pressure recording. The columns represent the "hPa" (0, ±2, ±4) at specific
time. The "0" in the middle of this scale is equal to the current pressure and each change (±2, ±4) represents how high
or low in "hPa" the past pressure was compared to the current pressure.
