1.5 Barometric
This segment displays the current barometric pressure, a historical
graph of pressures, and a pictorial weather forecast.
When the arrow symbol
“
”
is in this segment, press SET key to shift
display absolute (ABS) or relative (REL) pressure. The absolute
pressure
is the pressure measured at your console’s location (altitude).
Relative pressure refers to the pressure measured by your console
(absolute), corrected to the value that would exist if your station was
located at sea level. The relative pressure is what is normally published
by official weather stations.
Below the pressure values there is a historical graph. This graph can be
configured to display 12 or 24 hours of history and will give you some
insight into how pressure has been changing. Falling pressures typically
indicate worsening weather (to come), and rising pressures indicate
good/better weather is to come.
Below the graph you will see a pictorial forecast for the next 12 hours.
If the arrow symbol
“
”
is in this segment, following information with
time stamp will appear on message panel:
1) Maximum relatively barometric pressure of the current day
2) Minimum relatively barometric pressure of the current day
3) Maximum relatively barometric pressure since last reset
