Set Indoor Temperature and Outdoor Temperature Units
Change Indoor Temperature Units
. Press the
SET
key to set the indoor and outdoor temperature
units. The indoor and outdoor temperature will begin flashing. Press the
+
.to alternate the display unit
between °C and °F.
5.1.4
Set Barometric Pressure
Note:
The weather station console displays two different pressures: absolute (measured) and
relative (corrected to sea-level).
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 if you were 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 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.

. Press the
SET
key to set the pressure units. The pressure units will begin
flashing. Press the
+
key to alternate between in Hg and hPa.
2.
Relative vs. Absolute Pressure Display
. Press the
+
key to alternate the display between
relative (rel) pressure and absolute (abs) pressure.

key or
MIN/MAX
key to change the relative pressure.
4.
Pressure Threshold.
Press the
SET
key to
change the pressure threshold. The pressure
threshold will be flashing.
Press the

key
to adjust the pressure threshold from 2.0 to 4.0
hPa/hr (the default is 2 hPa/hr).
5.
Storm Threshold.
Press the
SET
key to
change the storm threshold. The storm threshold will
be flashing.
Press the
+
key
to adjust the pressure threshold from 3.0 to 9.0 hPa/hr (the default
is 4 hPa/hr).
