DCF/WWVB/MSF

The DCF (rcc 77.5 KHz), WWVB or MSF time signal is an AM modulated time-of-day signal br

oadcasted by the Federal Go

ve

rnment of Germany

,

NIST from USA or National Physical Labor

atory . The time base is gener

ated from an atomic time gener

ator which is accurate to 10

 billions of one

second.

LCD

“L CD” is an acr

onym for ”Liquid Crystal Display”.  This is a common type of display scr

een used in televisions, computers, watc

hes, and digital

clocks. 

BAROMETER & BAROMETRIC PRESSURE 

A barometer is a device that measur

es the pressur

e of the air pushing on it—this measurement is called the bar

ometric pressur

e.  W

e don’t actu-

ally feel the barometric pr

essure because the air pr

essure is pushing equally in ev

ery dire

ction. 

RELATIVE AIR PRESSURE 

Relative

 air pressur

e is the same as the barometric pr

essure.  The calculation of r

elativ

e air pr

essure is a combination of the

 absolute air pressur

e

and the altitude. 

ABSOLUTE AIR PRESSURE 

Absolute air pressur

e is the actual air pressur

e on the barometer without r

egard to altitude. 

INCHES OF MERCURY (inHg) 

I    nches of Mer

cury is the common unit of measurement for air pr

essure in the United States. 

HECTOP

ASCALS (hPa) 

Hectopascals are the common units of measur

ement for air pressur

e in the International System (SI) of measurement.  The hectopa

scal holds the

same value 

Important Note:

The Professional w

eather station includes a base station (receiv

er), a tr

ansmitter unit, one wind dire

ction sensor , one wind sp

eed

sensor , one r

ain gauge, USB cable and a PC softwa

re

 package on CD-ROM.

An added feature of the Weather Station is the readout of all measured and display

ed time and weather data on a PC.
