Parameters
P838 Auto False-Echo Suppression Distance
Defines the range of Auto False-Echo Suppression (P837) to use for ignoring false
echoes. (Units are defined in P005.)
Determine the actual distance from the transducer face to the material surface. Subtract
0.5 m from this distance, and enter the result.
Set Up:
1. Perform this function when the vessel is empty or nearly empty.
2. Determine actual distance from transducer face to material level.
3. Select P838 and key in [distance to material level minus 0.5 m].
4. Press ENTER .
5. Select P837.
6. Press 2 and then press ENTER . P837 will revert to 1 (use Learned TVT)
automatically after a few seconds.
P839 TVT Hover Level
Defines (in percent) how high the TVT curve is placed above the profile, relative to the
largest echo. When MultiRanger 100/200 is located in the center of the vessel, lower this
parameter to prevent multiple echo detections.
