Reference A-Scan |
: |
Reference
A-Scan pattern of standard test object can be saved and recalled in the
background for easy comparison during testing. |
| DAC |
: |
Dynamic DAC
curve can be Digitally plotted(Smooth parabolic curve) on screen with
selectable additional offset curves From 0 to 14db in
0.1db selectable steps. DAC curve can be plotted using minimum 2 to maximum 10 points
. |
|
DGS |
: |
Defect size evaluation based on 18
predefined probe data and one custom probe set-up per
memory location. Defect
size is directly displayed in ERS value(Equivalent
Reflector Size). |
|
AWS |
: |
Built-in software for evaluation of defects in accordance
with AWS Standards.(AWAD1.1/D1.5) |
Digital
Readout and Trig. Function |
: |
Thickness/Depth
can be displayed in digital readout when using a normal probe and
Sound path, Surface Distance and Depth of echo signals
of GATEa / GATEb are directly displayed when
angle probe is in use. Measurement point can be selected
to be Peak or Flank. Echo height,ERS value,dB diff of DAC/ DGS
curve to single height, Echo height with respect to DAC in
terms of percentage or in dB can be
measured,T-Minimum,Travel distance can be measured when
encoder is connectd and time of travel during Freerun
B-Scan. |
