5.12Setting the flaw location calculation

When using angle-beam probes, the flaw location can be automatically calculated. The following values are indicated on the display:

•Sound path

•Reduced projection distance: The distance from the front edge of the probe to the location of the flaw, projected on the surface

•Depth: Distance from flaw location to surface

The illustration on the next page shows the relationship between these values.

HNote:

The gate must be enabled and the MEASURE function set to “0 TO 1st“.

–With U go to center function table.

All the necessary functions are available in the right group.

P	projection distance
PR	reduced projection distance

Xdistance probe edge – beam index point

S effective sound path

D distance flaw location – surface
