To enable pressure based
Wave Recording
, make sure
to check the
Pressure based wave
in the wave module
selection, refer Figure 2-1.
Open the
Pressure wave
tab and insert the
number of
samples
in the wave record from the drop-down menu,
refer Figure 2-2.
Note that the length of the wave record is specified as
Samples in wave record. Thus, if the number of
samples is set to 2048 the duration of the wave record
is 1024 seconds since the pressure is sampled 2 times
per second (2Hz sample rate).
A graphic view illustrates the recording interval (green
cells) and the wave duration (blue cells), both in
seconds.
From the drop-down menu, insert the
Approximate
distance from the seabed to the surface
.
NOTE!
If the instrument is deployed in a fixed bottom frame mooring, it is recommended to enter zero in
the
Approximate distance from seabed to surface field
. The wave software will then calculate the
deployment depth and use this value both as absolute water depth and deployment depth in the
calculation of the wave parameters.
The Recording Interval is set in the Interval Configuration.
