Example 2:
The calibrated absolute pressure from a calibrated
pressure sensor, or actual absolute pressure is
968.8hPa.
The uncalibrated or measured absolute pressure
measured by the weather station is 971.4hPa.
Offset = 968.8– 971.4 = -2.6hPa
Enter the absolute pressure offset -2.6hPa
Note:
The absolute pressure offset will also affect the
relative pressure. To adjust the relative pressure, only
(independent of the absolute pressure), see 5.1.
Normally, you would not calibrate the absolute pressure
because it is difficult to obtain a calibrated source. The
preferred method is to calculate relative pressure to an
official source near you, as described in Section 4.3.2.
During calibration mode, press
LIGHT/SNOOZE
to exit
calibration mode.
The calibration offsets can be adjusted in the ranges
