Siemens LR 460 instruction manual Parame, Echo detection position, Echo Sampling Window

3.5.2.4.Narrow Echo Filter (default 0) Filters out echoes of a specific width.

Values	0 = OFF
	greater = wider
Related	•	3.6.2.1. Echo Confidence Long
Parameters	•	3.5.2.5. Reform Echo (default 0)

To remove a false echo from the Echo Profile, take its width in mm and multiply it by 0.014. Enter the result.

For example, to filter out a spike with 500 mm width enter 7 (the sum of 500 x 0.014).

When a value is keyed in, the nearest acceptable value is entered. 3.5.2.5. Reform Echo (default 0)

Smooths jagged peaks in the echo profile. Reforms fragmented echoes into one echo.

Values	0 = OFF
	Greater = Wider
	Recommended range 10 to 20: higher is not recommended.

	•	3.5.2.3. Echo Marker

Use this feature when monitoring solids, if the reported level fluctuates slightly even though the monitored surface is still.

Enter the amount of smoothing required. When a value is keyed in, the nearest acceptable value is entered.

3.5.2.6. Echo detection position

The point on the selected echo from which the measured value is taken.

		RISING

3.5.3.Echo Sampling

3.5.3.1.Window.

A "distance window" centered on the echo, used to derive the reading. When a new measurement is in the window, the window is re-centered and the reading is calculated .

When the value is 0, the window is automatically calculated after each measurement.

•For slower Measurement Response values, the window is narrow.

•For faster Measurement Response values, the window becomes progressively wider.
