ABSOLUTE PRESSURE NUMBER
Absolute Pressure Number: Barometric Pressure is read by
the forecast station. Since this number is absolute pressure it
may not be the same as a local reporting station that reads in
relative pressure.
Note: The number cannot be calibrated.
Unit of Measure: (InHg or hPa):
Hold the HISTORY button to switch from InHg (inches or
mercury) or hPa (Hecto Pascal).
PRESSURE HISTORY
1. Press the HISTORY button to view numeric pressure
history.
2. 0 is current pressure. -1 through -12 reflects the pressure
history in one-hour increments.
12 HOUR PRESSURE HISTORY GRAPH
The bar chart indicates the pressure trend over the last 12
hours.
The columns represent the pressure change readings at
specific times.
The “0” is equal to the current pressure and each bar
represents how past pressure was compared to the current
pressure.
Read the graph from left to right. If the bars are rising, it
means that the weather is getting better due to the increase
of air pressure.
If the bars go down, it means the air pressure has dropped
and the weather is expected to get worse from the present
time.
Note: The bar graph will scroll
to prevent LCD burnout.
