Figure 86 Reference Reflector
After pressing [F1] at the DGS/AVG Parameter Setup menu, the live A-Scan screen
appears as shown above. The operator must bring the echo from the reference reflector to
80% Full Screen Height and press [F1] “REF” to capture the echo. Once the reference
echo has been captured, the instrument adjusts the gain as needed and draws the DGS/
AVG curves on the screen. This is shown below:
