5.4. Offsets
Offsets are applied in the Profiler application by selecting
Position
from the
Application Tools
menu (or by right-clicking on Profiler main screen).
There are separate offsets for Master and Slave Profiler heads.
Rotational (
R
) Offset
The Profiler(s) should be mounted with the
LED and fill screw on the housing facing
directly downwards. If there is any angular
imperfection with this mounting then this
should be corrected using the R offset.
These corrections will be accounted for in the
calculation of mean altitude.
Vertical (
Y
) Offset
It will be necessary to produce a mean altitude
calculation that is relative to a particular point
on the vehicle/platform (for example, the skid).
If the Profiler(s) are mounted above this
point then this height difference should be
calculated and entered as the
Y
offset. This
should be performed for both Profilers as they
may be mounted at different heights. The
Y
offset will be included in the calculation of
Mean Altitude.
Horizontal (
X
) Offset
Sets the distance from the centre of the vessel
for each Profiler head. Required to obtain an
accurate profile of the seabed which takes into
account the vessel beam (if the Profilers are
mounted at the widest point).
