10. DCF RECEPTION

a) General Information

The DCF signal is a signal that is sent by a
transmitter in Mainflingen (near Frankfurt on the
Main). Its range is up to 1,500 km and if
transmission conditions are ideal even up to
2,000 km.
Among other things, the DCF signal includes the
precise time (theoretical deviation of 1 second
in a million years!) and the date.
This means you do not have to switch manually
between daylight savings time and normal time
at the weather station; the time is adjusted
automatically.
The first DCF reception attempt is performed if you have set the barometric pressure
and altitude units and the altitude and after the weather station has completed
search for the outdoor sensors.
Search for the DCF signal and its evaluation will take at least 5 minutes. Do
not move the weather station during this time and do not press any buttons.
More reception attempt are performed at midnight, 03:00 a.m., 06:00 a.m. and
noon. A single successful reception per day will keep the deviation of the quartz
clock in the weather station below a second.
