Parameters
2.2.3.5.3. Min. Sensor Value (MIN. SENSOR VAL.)
The minimum value the device can measure in Sensor units.
2.2.3.5.4. Max. Sensor Value (MAX. SENSOR VAL.)
The maximum value the device can measure in Sensor units.
2.2.3.6. Noise
2.2.3.6.1. Echo Confidence
Indicates echo reliability: higher values represent better echo
quality. The display shows the echo confidence of the measurement
echo from the last shot. Confidence Threshold defines the minimum
criterion for echo confidence.
In PDM, open the menu View – Echo Profile.
2.2.3.6.2. Echo Strength
Displays the absolute strength (in dB referenced to 1 μV rms) of the
echo selected as the measurement echo.
In PDM, open the menu View – Echo Profile.
2.2.4. TVT (Auto False Echo Suppression) setup
First SITRANS LR260 learns the echo profile. Then the learned profile, or part of
the learned profile, is used to screen out false echoes. See Before Auto False
Echo Suppression on page 63 and After Auto False Echo Suppression on page
63 for examples.
2.2.4.1. TVT Type
Selects the TVT shaping type to be applied to the echo profile to extract
the true echo.
Values (view only) 0 to 99 dB
