5.18 Distance-amplitude correction 

(DAC)

The USM Go has an optional DAC function for the echo 
evaluation by means of the distance-amplitude correc-
tion (DAC). 

Due to the angle of beam spread and the sound attenu-
ation in the material, the echo height of equally sized re-
flectors depends on the distance to the probe. 

A distance-amplitude correction curve, recorded using 
defined reference reflectors, is a graphical representa-
tion of these influencing factors. 

If you use a reference block having artificial flaws to re-
cord a DAC curve, you can use this echo amplitude for 
the evaluation of a flaw without any further corrections. 
The reference block should be made of the same mate-
rial as the test object. 

The time-corrected gain TCG increases the gain in dis-
tance sensitive mode so that all reference echoes reach 
80 % screen height. The amplitude evaluation of echo 
indications is made in relation to the first reference echo.

– Switch to the second operating level.

– Select the function group 

EVAL

.

– Select the function 

EVAL MODE 

and press a function 

key to choose 

DAC/TCG

.

– Switch back to the first operating level. The function 

group 

DAC/TCG

 is now displayed there.

If a stored DAC curve exists, it becomes effective now.
