18.5 Upper Limit of the Sound Speed
When the plausibility of the signal is evaluated, it will be checked if the sound speed is
within a defined range. The upper limit used for the evaluation is the greater of the follow-
ing values:
• fixed upper value, default: 1 848 m/s
• value of the sound speed curve of the medium at the operating point plus offset, default
offset: 300 m/s
In the SuperUser mode, the values can be defined for media that are not contained in the
data set of the transmitter. Select Special Funct.\SYSTEM settings\Measur-
ing\Miscellaneous. Press ENTER until the menu item Bad soundspeed is dis-
played.
Enter for each measuring channel the max. signal amplifi-
cation. Enter 0 (zero) if no limit of the signal amplification is
to be used.
range: 0...255
Press ENTER.
Attention! The limit of the signal amplification is still active after the deactiva-
tion of the SuperUser mode.
Enter for each measuring channel the fixed upper limit of
the sound speed. Enter
0 (zero) to use the default value.
range: 0...3
000 m/s 
default: 1 848 m/s
Press ENTER.
Enter for each measuring channel the offset. Enter 0 (zero)
to use the default value.
rangeich: 0...900 m/s
default: 300 m/s
Press ENTER.
example: fixed upper value of the sound speed thresh.: 2 007 m/s
offset: 600 m/s
value of the sound speed curve at the operating point: 1 546 m/s
As 1 546 m/s + 600 m/s = 2 146 m/s is greater than the fixed upper value
2 007, this value will be used as the upper limit of the sound speed when
the plausibility of the signal is evaluated.
