I checked a forging(Std EN 10228-3 class-3) with 2 MHZ and 4 MHZ normal probe.when I use 2 MHZ probe it shows continuous indications of 1.6 to 3 mm dia ERS while with 4 MHZ probe there is no indication on the screen.
All the indication falls in the category of recordable indications but it also create a doubt of laminar indication when doing interpretation with 2 MHZ Normal probe .
Please suggest what should I do ?
