7. Applications

7.1 Automatic Thickness Measurement

See also 5.2.2 for GATE 2 automatic thickness measurement function.

1. Adjust appropriate VELOCITY and

Time Base.

2. Switch to the GATES menu.

3. Adjust

minimum

THICKNESS

value. The minimum THICKNESS

value

shall

less

than

expected thickness value to be

measured.

4. Place transducer on the subject to

be measured and get a waveform with at least two consecutive back-wall

echoes.

5. Adjust GATE 1

- vertical level to cross both echoes to be measured,

- horizontal position and width so as to cover both echoes to be measured.

6. Switch GATE 2 to the THICKNESS AUTO 1P-1P mode

7. The measured thickness value will be displayed in the Status window with

dark blue colour.
