pressure (the pressure your location would be at if located at sea-level) is generally higher than your

measured pressure.

Thus, your absolute pressure may read 28.62 inHg (969 mb) at an altitude of 1000 feet (305 m), but

the relative pressure is 30.00 inHg (1016 mb).

The standard sea-level pressure is 29.92 in Hg (1013 mb). This is the average sea-level pressure

around the world. Relative pressure measurements greater than 29.92 inHg (1013 mb) are

considered high pressure and relative pressure measurements less than 29.92 inHg are considered low

pressure.

To determine the relative pressure for your location, locate an official reporting station near you (the

internet is the best source for real time barometer conditions, such as Weather.com or

Wunderground.com), and set your weather station to match the official reporting station.

To change the relative pressure when flashing, press the + key or - key to increase or decrease the

relative pressure setting to match the official reporting station.
