S75617 Barometric Pressure Readings

How often does the pressure update?
• Barometric pressure is read by the station every 12 seconds.
• Default reading is: InHg 29.92 InHg (1013 hPa)
• The pressure number is programmable in the settings menu.

What are the arrows by the pressure?
These are Pressure Trend Arrows:
• Up Arrow indicates rising pressure over the past 3 hours
• Down Arrow indicates falling pressure over the past 3 hours

Why does the pressure graph blink?
The bar chart will constantly scroll for visual interest.
This scroll feature cannot be turned off.
• The bar graph shows the recorded air pressure over the past 24-hours.
• The horizontal axis shows the hours at increments of:
-24 hours, -18 hours, -12 hours, -9 hours, -6 hours, -3 hours, and 0 hours (current).
• Each bar on the graph represents a value of 1 inHg or 0.03 hPa
• The “0h” on the horizontal axis indicates the current hour, thus the current air pressure also.


Reading the bar graph:
• 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.
• 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.
