Auto False Echo Suppression - Siemens SITRANS Probe LU Quick Start Manual

Auto False Echo Suppression

Enables a "learned" TVT curve to be used in place of the default TVT curve. Use this feature to
ignore false echoes on the echo profile. Set Range (Auto False Echo Suppression Distance)
first, then set Auto False Echo Suppression.
Range (Auto False Echo Suppression Distance)
Defines the endpoint of the Learned TVT distance.
1. Rotate the instrument for best signal (lower false-echo amplitude).
2. Go to Input > Detailed Setup > TVT setup > Distance.
3. Determine the actual distance from the reference point (transducer face) to the material
surface.
4. Subtract 0.5 m (20") from this distance, and enter the result.
Set Auto False Echo Suppression
1. Open the menu Device – Auto False Echo Suppression and select the option to change it.
2. Select Learn. The device will automatically revert to On (Use Learned TVT) after a few
seconds.
