View the Pressure, Temperature and Humidity Bar Charts
The pressure bar graph shows barometric pressure variations over the past 24 hours. This is very useful for
understanding the Barometric trends that are used in weather forecasting. Each bar icon represents 0.06 InHg.
Alternatively, the bar chart can be used to display 24 hour trend data for sea level pressure, outdoor temperature or
outdoor humidity (channel 1 only).
1.
Select the Pressure and Weather Forecast window.
2.
Hold
the ALARM/CHART button to change the bar chart
title
(right bottom corner).
3.
Alternate between Pressure, Outdoor Temperature (thermometer icon) and Relative Humidity (dew

The single bar on the far right indicates rising or falling trend.
All the bar charts are read from left to right.
The left is the oldest history data.
Reading from left to right indicates the rise and fall of the reading.
The bar chart will constantly scroll to avoid LCD burnout.
Weather Forecast Icons
The weather forecasting feature is estimated to be 70% accurate. The weather forecast is based solely upon the change
of air pressure over time. The icons are predicting 12-24 hours in the future, not current conditions. It may be sunny out
your window, but the pressure is falling so the forecast station will show clouds with rain icon. The SUNNY icon indicates
clear weather, even when displayed during the night-time.The icons displayed forecast the weather in
terms of getting
better or worse, and not necessarily sunny or rainy
as each icon indicates.
Note:
After initial set-up, icons for weather forecasts should be disregarded for the next 48-60 hours. This will allow
sufficient time for the weather station to collect air pressure data at a constant altitude and result in a more accurate
forecast.
