signal from the NIST Atomic clock in Boulder, Colorado. A team
of atomic physicists continually measure every second of every
day to an accuracy of ten billionths of a second a day. These
physicists have created an international standard, measuring a
second as 9,192,631,770 vibrations of a Cesium 133 atom in a
vacuum. This Weather Station regulates the WWVB transmitter.
SET-UP GUIDE
I. BATTERY INSTALLATION
1. Remove the battery
cover—insert a
solid object in the
space provided at
the lower-central
position of the
battery cover, push
up and pull out on
the battery cover.
2. Observe the correct polarity and install 3
AA batteries.
3. Replace the battery cover.
Note:
Immediately after the batteries have been installed
each LCD (Liquid Crystal Display) will flash. Within a
few seconds the indoor temperature, indoor relative
humidity, and the weather icons (sun and clouds) will be
displayed. If not, then remove batteries for 10 seconds
and reinstall. The time will show 12:00 am and start
searching for the signal. If it successfully receives the
time signal (usually at night), it will display the correct
time (default is Eastern)
