Krautkramer USM 35X
Issue 01, 04/2005
5-61
Operation
Distance-amplitude curve (only USM 35X DAC and USM 35S)
5.18 Distance-amplitude curve
(only USM 35X DAC and
USM 35S)
H
Note:
The DAC function is available as a fixed function in the
second operating level on the USM 35X DAC. With the
USM 35X S, the DAC function can be additionally
switched over to DGS evaluation mode.
Due to the angle of the sound beam spread and to the
sound attenuation in the material the echo height of
reflectors of equal size depends on the distance to the
probe.
A distance-amplitude curve, which is recorded with
defined reference reflectors, graphically displays these
influences.
If you use a reference block having artificial flaws when
recording a DAC you will be able to apply these echo
amplitudes for the evaluation of discontinuities without
any further correction. The reference block should be
made of the same material as the test object.
You will find the functions for the distance-amplitude
curve in the function group
DAC
. If required, select the
setting
DAC
in the function group
EVAMOD
first.
– If required, go to the third operating level.
– Select the function group
CFG2
.
– Switch the function
EVA-MOD
over to the setting
DAC
.
– Go to the second operating level.
– Select the function group
DAC
