Read from left to right, the Pressure History Graph indicates the rise and fall in air pressure over the past 24
hours.
• The "0h" on the horizontal axis indicates the current hour, thus the current air pressure also.
• At every full hour the current air pressure is used as a basis for the display of a new graph bar.
• Air pressure trends can be determined by simply glancing at the bar graph.
A. If the bars are rising (higher on the right than the left) then the air pressure has a rising trend, and the
weather should improve.
B. If the bars are dropping (lower on the right than the left) then the air pressure has a falling trend, and
the weather should worsen.
• The bar chart will constantly scroll to provide visual interest. This cannot be turned off.
• The Relative Pressure numbers represent the currect Barometric Pressure reading from the pressure
sensor inside the weather station.
• This number can be adjusted in the Settings Menu, to match your local reporting station.
• The Weather Forecast Icons are determined by the station's barometric pressure reading. Please allow
7-10 days for barometric calibration.
• This is your pressure at your stations' location and may vary slightly from your local reporting station.
• Six forecast icons use changing atmospheric pressure to predict weather conditions for the next 12-hours
with 70-75% accuracy.
• When Outdoor temperature is below 32˚F and the forecast is RAIN or T-STORM, the station will display
SNOW.
