DAC Curve Procedure in Ultrasonic Testing by Tonyo Ayshiyu is a document available to read on EtoBox.

1. Position an ultrasound probe at three locations on a test block and adjust the gain to mark echoes at 80%, 40%, and 20% of the screen height. 2. Repeat this for two more probe positions to create nine marking points. 3. Connect the nine points to create a distance amplitude correction (DAC) curve showing the relationship between probe location, gain adjustments, and echo amplitude. 4. The DAC curve compensates for differences in surface roughness between the test block and test material when performin
