9. The default relative atmospheric pressure value is 1013
mb/hPa (29.91 inHg), which refers to the average atmo-
spheric pressure.
10. When you change the relative atmospheric pressure
value, the weather indicators will change along with it.
11. The built-in barometer can notice the environmental
absolute atmospheric pressure changes. Based on the
collected data a forecast for the weather conditions in
the next 12 hours can be made. Therefore, the weather
indicators will change according to the detected abso-
lute atmospheric pressure after you operate the clock
for 1 hour.
12. The relative atmospheric pressure is based on the sea
level, but it will change with the absolute atmospheric
pressure changes after operating the clock for 1 hour.
18 Temperature display
Press the °C/°F button to switch between the temperature
display in °C or °F.
When temperatures of -40°C or below and humidity of 20%
or below are reached, the information "LO" is output for the
respective range.
At temperatures of 70°C or higher and a humidity of 90% or
higher, the information "HI" is displayed.
For values outside the measurable range "- -" is displayed.
When returning to a measurable temperature range, the
corresponding temperature is displayed again.
19 History record for the past 24 hours
The base station automatically records air pressure read-
ings from the last 24 hours.
If necessary, press the HISTORY button several times to dis-
play the history data for the hourly values (HOUR - up to 24
hours backwards) for the pressure one after the other.
