For angle beam probes, the available reflectors are:
• Side-drilled hole (SDH)
• K1-IIW block arc
•K2-DSC block
• Flat-bottom hole (FBH)
— Reflector Dia.
Used for angle beam inspections only. This allows you to define the diameter
of the flat-bottom hole (FBH) or side-drilled hole (SDH) used as a reference-
reflector. This size is required to properly position the DGS/AVG curve.
— DeltaVK
Used for angle beam inspections with reference-reflector K1-IIW or K2-DSC
blocks only. This correction value for the angle beam transducer can be found
listed on the DGS/AVG diagram for the selected transducer.
— DeltaVT
Transfer correction value, used to compensate in amplitude differences as a
result of coupling variation (surface condition) from the calibration block to
the test piece. EN 583-2:2001 provides methods for calculating transfer
correction.
— Reg. Level
The height of the main DGS/AVG curve. The curve represents the amplitude
from a flat-bottom hole with a diameter of the registration level at different
depths. This is usually equal to the critical flaw size for the application.
— Warning Levels
These are the positions of up to three secondary DGS/AVG “warning” curves
compared to the position of the main DGS/AVG curve. If any of these values
are set to zero, the warning curve is turned off.
— ACV Specimen
This is the attenuation value in dB/m for the test piece (specimen). In some
cases, it is necessary to calculate the relative attenuation within the test piece
and enter the value here.
— ACV Cal Block
This is the attenuation value in dB/m for the calibration block. In some cases,
it is necessary to calculate the relative attenuation within the calibration block
and enter the value here.
