Indication of signal amplification
This menu is used to display the amplification level of the
received ultrasonic echo. The function can give an indication
og the strength of the received echo.
If the amplification level is low (below. 20 dB), the echo
strength is good and vice versa.
A high amplification level (max. 50 dB) indicate that the
ultrasonic echo is weak (foam or waves).
High amplification may in certain situations create other
problems with electrical noise from other equipment at the
installation site.
The amplification level is displayed immediately.
(The level is displayed in dB)
