Alarm Mode - Opes OP-WS01/WH1170 Instruction Manual

To compare pressure conditions from one location to another, meteorologists correct pressure to
sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected
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 Opes™ Weather Station to match the official reporting station.
To change the relative pressure when flashing, press the + key or MIN/MAX key to increase or decrease
the relative pressure setting to match the official reporting station.

a. When a set weather alarm condition has been activated, that particular alarm will sound and flash for 120
