Glossary of Common Terms

DCF/WWVB
The DCF or WWVB time signal is an AM modulated time-of-day signal broadcasted by the Federal
Government of Germany or NIST from USA. The time base is generated from an atomic time generator
which is accurate to 10 billion of one second.
LCD
"LCD" is an acronym for "Liquid Crystal Display". This is a common type of display screen used in
televisions, computers, watches, and digital clocks.
BAROMETER & BAROMETRIC PRESSURE
A barometer is a device that measures the pressure of the air pushing on it—this measurement is called
the barometric pressure. We don't actually feel the barometric pressure because the air pressure is
pushing equally in every direction.
RELATIVE AIR PRESSURE
Relative air pressure is the same as the barometric pressure. The calculation of relative air pressure is a
combination of the absolute air pressure and the altitude.
ABSOLUTE AIR PRESSURE
Absolute air pressure is the actual air pressure on the barometer without regard to altitude.
INCHES OF MERCURY (inHg)
An inch of Mercury is the common unit of measurement for air pressure in the United States.
HECTOPASCALS (hPa)
Hectopascals are the common units of measurement for air pressure in the International System (SI) of
measurement. The hectopascal holds the same value
