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

Calibration
1. Open the menu Device – Sensor Calibration and select the tab Dry Calibration. (Click on
Additional Information to see the schematic showing the PROFIBUS parameters.)
2. Enter the new value for Low Calibration Point (default units are meters).
3. Enter the corresponding value for Low Level Point in percent (default is 0).
4. Enter the new value for High Calibration Point (default units are meters).
5. Enter the corresponding value for High Level Point in percent (default is 100).
6. Click on Transfer.
7. SITRANS Probe LU is now ready to operate.

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.
