RELATIVE PRESSURE RE FERENCE VALUE:
Note:
For an exact measurement, it is necessary to adjust the
barometer to the local relative air pressure (related to elevation
above sea level)
. Ask for the current air pressure of the home area
(local weather service, the World Wide Web, calibrated instruments in
public buildings, airport). The default reference pressure value is 29.91
inHg.
The relative air pressure can be manually set to another value within
the range of 27.17 to 31.90 inHg (920 to 1080 hPa) for a better
reference.

W EATHER TENDENCY SENSITIVITY:
The sensitivity of the weather forecast icons to changes in air pressure can be set manually.
Smaller values result in a more sensitive forecast. The switching sensitivity value can be set to
.06, .09, or .12 inHg (2, 3 or 4 hPa). Select lower values (.06) for high humidity areas like the
coastline. Select high numbers (.12) for dry areas like the desert. The default value is 0.09 inHg.
1. The sensitivity value will flash.
2. Press the

STORM W ARNING SENSITIV ITY:
A storm warning is displayed by flashing of the
down
weather tendency arrow when the air
pressure decreases a specified amount over six hours. The sensitivity value for the storm
warning display can be set between .09 inHg to .27 inHg (3hPa to 9hPa). The default value is
0.15 inHg.
1. The sensitivity value will flash.
