3. e Illumination may not turn on right away if you raise the watch to your face while a barometric pressure or altitude measurement operation is in progress Questions amp Answers Question How can the barometer be used to predict weather Answer Barometric pressure indicates changes in the atmosphere and by monitoring these changes you can predict the weather with reasonable accuracy Rising atmospheric pressure indicates good weather while falling pressure indicates deteriorating weather conditions The barometric pressures that you see in the newspaper and on the TV weather report are measurements corrected to values measured at 0 m sea level Question How does the altimeter work Answer Generally air pressure and temperature decrease as altitude increases This watch bases its altitude measurements on International Standard Atmosphere ISA values stipulated by the International Civil Aviation Organization ICAO These values define relationships between altitude air pressure and temperature Altitude Air Pressure Temperature 616 hPa About 8 hPa per 100 m 11 C 3500 m 7 5 3000 m 701 hPa About 9 hPa per 100 m z4 5 C 2500 m About 6 5 C 2000 m 795 hPa About 10 hPa per 100 m 2 Perm 1500 m 1000 m 899 hPa About 11 hPa per 100 m 8 5 C 500 m i 1013 hPa About 12 hPa per 100 m 15 C 14000 ft 12000 ft 10000 ft 8000 ft 6000 ft 4000 ft i 2000 ft 19 03 inHg About 0 15 inHg per

7. About Barometric and Temperature Measurements e Barometric pressure and temperature measurement operations are performed as soon as you enter the Barometer Thermometer Mode After that barometric pressure and temperature measurements are taken every five seconds e You also can perform a barometric pressure and temperature measurement at any time by pressing B in the Barometer Thermometer Mode CASIO Operation Guide 3144 Altimeter The watch s altimeter uses a pressure sensor to detect current air pressure which is then used to estimate the current altitude based on ISA International Standard Atmosphere preset values You also can specify a reference altitude which the watch will use to calculate your current altitude based on the value you specify Altimeter functions also include storage of measurement data in memory You also can measure the altitude differential change from a specific reference altitude Specifying the reference altitude is as simple as pressing a single button to reset the reference altitude to zero Important e This watch estimates altitude based on air pressure This means that altitude readings for the same location may vary if air pressure changes e The semiconductor pressure sensor used by the watch for altitude measurements also is affected by temperature When taking altitude measurements make sure the watch is not subjected to temperature changes To avoid the effect of sudden temperature
8. The watch will start altitude measurement automatically and display the result e It can take up to four or five seconds for the altitude reading to appear after you enter the Altimeter Mode 2 If you want the altitude value and altitude a TERE T graph to be updated in accordance with the altitude measurement type interval and Altitude differential duration you have selected leave the watch pointer in the Altimeter Mode e f you want to restart the altitude measurement operation at any point press 3 To stop the altitude measurement operation press to exit the Altimeter Mode Altitude graph Current altitude Notes Normally displayed altitude values are based on the watch s preset conversion values You also can specify a reference altitude if you want See Specifying a Reference Altitude Altitude is displayed in units of 5 meters 20 feet e The measurement range for altitude is 700 to 10 000 meters 2 300 to 32 800 feet The measured altitude may be a negative value in cases where there is a reference altitude value set or because of certain atmospheric conditions The displayed altitude value changes to meters or feet if a measured altitude falls outside the measurement range The altitude value will be displayed again as soon as the measured altitude is within the allowable range You can change the measurement unit for displayed altitude values to either meters m
