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 HydroRanger 200 (all models) is located in the center of the vessel,
lower this parameter to prevent multiple echo detections.
