5 Operation Flaw position calculation with angle-beam probes
5-46 Issue 2 (12/2013) USM 36
Example: Object thickness 20 mm
● Angle of incidence 45°,
K = 1, 1. Reflection after 20 mm
● Angle of incidence 60°,
K = 1.73, 1. Reflection after
1.73 × 20 mm = 34.6 mm
● Angle of incidence 70°,
K = 2.75, 1. Reflection after
2.75 × 20 mm = 55.0 mm
● Angle of incidence 80°,
K = 5.67, 1. Reflection after
5.67 × 20 mm = 113.4 mm
– Select the function PROBE ANGLE .

THICKNESS
You can use the function THICKNESS to set the wall
thickness of the test object. This value is required for the
automatic calculation of the true depth of a reflection.
The adjustment range is 1.00 … 27940.00 mm.
You can set the value by coarse adjustment steps or by
fine adjustment (see Section
Coarse adjustment and
fine adjustment , page 4-11).
