• Enter for each measuring channel the offset. Enter zero to use the default value of
300 m/s.
• Press ENTER.
It is possible to display the valid range for the sound speed (SS=) in the lower line within
the program branch Measuring during the measurement. The second value (here:
2146 m/s) corresponds to the upper limit at the operating point.

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.
