Parameters
2.5.4.2. Far Range (HI RANGE)
Maximum distance from the reference point
2
, within which an echo
should be considered valid.
Echo Profile
Echo Confidence
Measures echo reliability. It displays the echo confidence of the
measurement echo from the last shot. Confidence Threshold defines the
minimum criterion for echo confidence.
Open the menu View – Profile.
Echo Strength
Displays the absolute strength (in dB above 1 µV rms) of the echo selected
as the measurement echo.
Open the menu View – Profile.
Noise Average
Displays the average ambient noise (in dB above 1 µV rms) of a noise
profile, as x.y. Noise level is a combination of transient noise and receiving
circuitry. After a measurement, the values from the previous noise shot
will be displayed.
Open the menu View – Noise.
Noise Peak
Displays the peak ambient noise (in dB above 1 µV rms).
Open the menu View – Noise.
Noise Minimum
Displays the minimum ambient noise (in dB above 1 µV rms).
Open the menu View – Noise.
Note: Far Range can extend beyond the bottom of the tank.
