6.4.2 Does the Wristop Computer show future trends in weather
conditions?
No, the Wristop Computer continually accumulates data on barometric pressure existent within a 3 to 6 hour
window and displays general barometric trends in weather based on the accumulated data.
6.4.3 What does "absolute pressure" and "relative pressure"
mean?
Absolute pressure is the actual pressure in any location at any given time. Relative pressure on the other hand
equals the corresponding pressure at sea level for a certain altitude that you are at. For example, if you are at
an altitude of 1,000 m/3,300 ft the absolute pressure normally is around 900 mbar/26.60 inHg. The relative
pressure at sea level would then be around 1,013 mbar/29.90 inHg.
6.4.4 What is temperature compensation?
When the unit is temperature compensated, the altitude measurement of the unit is not affected by the
temperature of the unit itself. The unit can be worn on your wrist or placed on a table – it will in either case give
you the proper altitude reading providing the weather conditions have not changed. All Suunto Wristop Computers
are temperature compensated within the range –5 to 140 ° F / - 20 to +60 ° C.
6.5 COMPASS
6.5.1 What is the purpose of the rotating outer bezel?
The purpose of the rotating bezel is that people can use the instrument as a regular base plate compass if they
want to, and use the bezel to e.g. indicate North when in the bearing tracking mode or leaving the compass
display for another mode.
Also, it can be used to manually follow your vertical progress by using the lubber's line on the bezel to mark the
altitude from where you want to follow your progress (i.e. a zero point). You could also mark a certain altitude,
which is graphically shown by the segments on the circumference, to get an intermediate difference
measurement. However, the bezel is mainly related to the compass function.
