Set reference altitude (real altitude) 3280 ft
Displayed altitude 9840 ft
Real outside temperature +36.3 ºF +18.9 ºF
Normal (table) temperature +47.3 ºF +23.9 ºF
Temperature difference (= real - normal) -9 ºF -5 ºF
Sum of temperature offsets -9 ºF + -5 ºF = -14 ºF
CHAPTER 4 BAROMETER MODE
The Barometer provides you with:
• An adjustable unit of measure hPa or inHg; hPa range 300 to 1100 hPa, inHg range 8.90
to 32.40;
• A resolution of 1 hPa or 0.05 inHg;
• A one hour interval measuring to estimate barometric trend;
• An automatic 4-day memory of atmospheric pressure;
• Temperature compensation (temperature does not effect the pressure within the speci-
fied temperature range);
• A temperature range -20º to 60ºC or -5º to 140ºF;
• A temperature resolution of 1º C or F; and
• An Altimeter-Barometer use feature. Refer to Chapter 3, Altimeter-Barometer Use for
more information.
NOTE: To acquire true temperature reading, take the Observer away from wrist and allow it
to adjust to the ambient temperature for 15 minutes.
