Parameters
2.2.4.3.7. Reform Echo
Smooths jagged peaks in the echo profile. Reforms fragmented echoes
into one echo.
2.2.4.5. Noise
2.2.4.5.1. Echo Confidence
Indicates echo reliability. It displays the echo confidence of the last
measurement. Echo Threshold defines the Echo Confidence minimum
criterion for echo confidence. Echo confidence must be greater than Echo
Threshold to be accepted as valid and evaluated for an echo.
In PDM, open the menu View – Echo Profile.
2.2.4.5.2. Echo Strength
Displays the absolute strength (in dB above 1 μV rms) of the echo selected
as the measurement echo.
In PDM, open the menu View – Echo Profile.
2.2.4.5.3. Noise Average
Displays the average ambient noise (in dB above 1 μV rms) of a noise
profile (view only). Noise level is a combination of transient noise and
receiving circuitry. After a measurement, the values from the previous
noise shot will be displayed.
Values
0 = OFF
greater = wider
Range: 0 to 50 mS
