GE Krautkramer USM 35X - Calculation of Flaw Position (Function Group TRIG)

Krautkramer USM 35X Issue 01, 04/2005 5-31
Operation
5.11 Calculation of flaw position
(function group TRIG)
In the function group TRIG you will find the functions for
setting the flaw position calculation when using angle-
beam probes.
– If required, go to the first operating level.
– Select the function group TRIG.
Calculation of flaw position (function group TRIG)
H Note:
Double assignment of the function X-VALU/COLOR.
Toggle between the two functions by repeatedly press-
ing the corresponding key
.
The functions in the group TRIG enable to automatically
calculate the (reduced) projection distance and the real
depth of the flaw in addition to the sound path S, and to
digitally display them in the measurement line.
• Projection distance PD:
distance of probe index (sound exit point) from the
position of the flaw, projected on the surface
• Reduced projection distance rPD:
distance of the probe’s leading face from the position
of the flaw, projected on the surface
• Depth d:
Distance between flaw position and surface
