5.25 JISDAC
The USM 100 has a DAC function for the echo evalua-
tion by means of the distance-amplitude correction
(DAC) and an additional class rating according to the
Japanese standard JIS Z3060-2002.
With the function JISDAC, you can activate a distance-
amplitude curve according to JIS including three evalu-
ation lines marked with the letters
L (low), M (medium),
and H (high). They are permanently connected to the
recorded DAC curve and shifted accordingly if the gain
is varied.
In addition, a class rating takes place. Flaw echoes are
evaluated according to their amplitude with reference to
their position within the set of curves:
Class I: Amplitude < Line L
Class II: Line L < Amplitude < Line M
Class III: Line M < Amplitude < Line H
Class IV: Amplitude > Line H
Activating JISDAC
– In the A-scan tap on the Evaluation icon to display
the function group.
– In the function Eval Mode select JISDAC .
– Set all parameters in this function group (see from
page 158).
