P067 Choose Peak (Software Revisions from 3.6.0)
This parameter is used to determine which echo is selected for processing.
DATEM software will detect all valid echoes i.e. all peaks that exceed DATEM
plus the Loss Limit Values (P81 & 82). The peak then chosen for processing will
be selected according to option chosen as detailed below.
Options: 1 = Best
2 = Largest
3 = First
Best
The first echo that appears above DATEM, plus the Loss Limit, will be weighted
according to the factor set in P049 Scale First (Default =40%) the peak then
chosen for processing will be the echo with the highest resulting peak after first
weighting has been applied.
Largest
The echo with the highest peak will be selected for processing, when this option
is chosen no weighting is applied to the first valid echo.
First
When selected, the First valid echo will be selected regardless of any other echoes
that are present.
P071 Update DATEM
This parameter determines whether DATEM is adaptive or not. When 0=No is
selected DATEM will be used but will not be adaptive and will remain at its last
known value. If 1 = Yes is selected DATEM will continually update to the
conditions seen in the vessel and eliminate any echo returns from unwanted
sources.
Options: 0 = No
1 = Yes
