DGS-AVG with GE SEB2-0º probe

Has anyone had problems with GE SEB2-0º DGS-AVG evaluation curves? In my case, the 3mm FBH signals from a reference block don't coincide with the corresponding USM35 DGS curve and the ERS sizing error is 1 to 2 mm at diferent depths.
Does anyone know anything about this?
Thanks!

If I understand correctly, DGS curve is for particular transducer. Use the GE Reference block it should match. different manufacturer there will be slightly different.

Confirm that you are using the curve for the SEB2 with zero-degree roof angle and not the curve for a standard SEB2-E, which has a roof angle.

Thanks S.Senthilkumar, but this only occurs with SEB2-0º DGS curve. With other probes DGS curves the results are correct.

Hi Mikel, which are the depths/soundpath to FBH's. Regards Theo

Hi Theo, the depths/soundpath to FBH's are 50, 80, 120 and 180mm. Have you any idea about the problem?

Hi Mikel,in my experience,there is no channel for SEB 2-0° in USM 35. So did you make DGS curve in custom channel?

Hi Mikel, I suggest you to make a cross-check of AVG diagram loaded in your equipment with paper AVG diagram of the probe.
