Example
fixed upper value of the sound speed (
thresh.
): 2007 m/s
offset
: 600 m/s
value of the sound speed curve at the operating point: 1546 m/s
As 1546 m/s + 600 m/s = 2146 m/s is greater than the fixed upper value 2007, this val
-
ue will be used as the upper limit of the sound speed when the plausibility of the signal
is evaluated.

Notice!
The defined upper limit of the sound speed remains activated after the deactivation
of the SuperUser mode.
