7.4.4 What is the duration readout?
the duration readout tells you how many hours and/or minutes the event recorded into the logbook lasted. for example, if you’re hiking
from 1 p.m. to 6 p.m. and the logbook is on during this time, the readout would show a duration of 05:00 hours.
7.4.5 What is the maximum capacity of total vertical ascent or
descent feet/meters in the logbook history?
The maximum figure that can be shown on the display is 29,999,999 representing feet or meters depending on the unit of measurement
set. This should be enough for most users: 29,999,999 meters is roughly three-quarters around the globe.
7.4.6 If hiking from a level of 5,000 ft down hill to 3,000 ft and
then back up to 8,000 feet, how is the Wristop Computer going to
read this or average it out?
there are several answers to this question related to different situations.
first, if you mean will Wristop computer show accurate altitude information when ascending back to 8,000 ft after having descended
to 3,000 ft from 5,000 ft, the answer is yes if the barometric pressure hasn’t been affected by weather changes. since the altitude is
shown based on the atmospheric pressure reading it will be affected by pressure changes. But if the conditions are the same, and the
reference altitude is set, the unit will show quite accurate readings.
Second, if what you mean is how the Wristop Computer calculates the information shown in the logbook, this is what it does: for the total
ascent during the log (the logbook recording has been activated by the user when starting out) it calculates the ascent from 3,000 ft to 8,000
ft, i.e. total ascent has been 5,000ft. for the descent it calculates the descent from 5,000 ft to 3,000 ft, i.e. total descent ,000 ft.
third, if thinking about the difference measurement function and how this is affected by the example situation, the Wristop computer
will show you the absolute difference between 5,000 ft and 8,000 ft (beginning and end). the fact that you’ve been down to 3,000 ft
in-between does not have an impact on the absolute vertical altitude difference between starting point and finish.
Last, the automatic 24-hour memory will show this information in the following way: Say you are starting out at 5,000 ft at noon, and
then it takes you 2 hours to descend to 3,000 ft, and another five hours to reach 8,000 ft. The scrollable displays in the 24-hour memory
shows you the altitude 5,000 ft at 12:00 am, e.g. 4,000 ft at 1 p.m., 3,000 ft at 2 p.m., e.g. 4,000 ft at 3 p.m., 5,000 ft at 4 p.m., 6,000 ft
at 5 p.m., 7,000 ft at 6 p.m. and then 8,000 ft at 7 p.m.
these are the different cases in which the example situation will affect the readings of the Wristop computer. most important to remember
