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 (1013.2hpa). This is the average sea-level pressure around the
world. Relative pressure measurements greater than 29.92 inHg (1013.2hpa) 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), and set your weather station to match the official reporting
station.
2.0 Rainfall Calibration (1 Hour, 24 Hour, Daily, Monthly, Total). Press the SET key again and the Rain
Calibration value will begin flashing (the default is 1.0). Press the [+] or [-] button to adjust the rain calibration
factor from 0.75 to 1.25, where:
Calibrated Rain = Calibration factor x Measured Rain
Discussion: The rain collector is calibrated at the factory based on the funnel diameter. The bucket tips every
0.01” of rain (referred to as resolution). The accumulated rainfall can be compared to a sight glass rain gauge with
an aperture of at least 4”.
Note: that debris and insects can collect inside the tipping mechanism (they make a good spiders nest).
Carefully remove the funnel and inspect the tipping mechanism for debris prior
to calibration.
