Siemens 200 P838 Auto False-Echo Suppression Distance, P839 TVT Hover Level, Set Up

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.)

Values	Range	Maximum range:
	(depends on model)	0.000 to 15 m (50 ft)
	Default	1.000 m (3.28 ft)

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.

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.

Values	Range	0 to 100%
	Default	33 (%)
