Echo-Strength Bargraph
The green bargraph display indicates ultrasonic coupling-strength :
A single flashing bar means there is no contact at all
One or two bars, plus a flashing bar, means there is not enough contact to obtain three
echoes
This indicates either poor contact, or badly corroded material
This can also occur if the Probe membrane has been fitted incorrectly
Three bars, plus one flashing bar, means there is good contact, but a valid triple-echo
measurement has not been obtained
This probably indicates badly corroded material
Four bars, plus one flashing bar, shows an accurate triple-echo measurment
