a) General
As mentioned there, the multi-compass uses a pressure
sensor for measuring height which measures the air pres-
sure of the environment. As the air pressure changes con-
stantly, the display deviates from the actual height.
N
If you are located at a point of a known height (e.g. at the
starting point of a wandering, height stated on a map, e.g.
"400 m"), the multi-compass will presumably display a dif-
ferent value (e.g. "410m"). The next day, a value of "390m"
could be displayed because the air pressure has changed in
the meantime.
M
Therefore, before commencing your wandering, set a refer-
ence value (see section 7, h) if you know the actual height
at the starting point of the wandering.
L
This will mean that the exactitude of the subsequent display
or alteration in height is improve
For programming, observe section 7. h).
d.
Please observe:
Changes in the air pressure during measuring
lead to the fact that the display of the height can
deviate from the actual height. The altimeter of
the multi-compass is e not suitable for measure-
ments for which the exactitude of the height is
critical!
