6.3.3 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.

6.3.4 Is the Wristop Computer temperature compensated?

Yes, the Wristop Computer is temperature compensated, which means that for the temperature range specified (-5 to
+140°F/-20 to +60°C), the instrument will show accurate pressure. Within this range, the temperature has no effect on
the atmospheric pressure reading.
Temperature compensation does not, however, mean that the temperature reading isn't at all effected by body heat. Body
heat will affect the temperature reading, and to get the correct temperature reading of the environment remember to take
the Wristop Computer off your wrist and wait about 15 minutes for it to stabilize and show the correct temperature of the
surroundings.

6.4 COMPASS

6.4.1 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. The bezel is also used for determing the favored end of the start line in a race. (for more information, see chapter
5 Compass mode)
6.4.2 Where do I find the correct declination for my area so I can
set my Wristop Computer?
Local declination, either E or W, is usually marked on maps with either one-degree or half-degree accuracy.
