PCT No. PCT/DE91/00543 Sec. 371 Date Aug. 28, 1992 Sec. 102(e) Date Aug. 28, 1992 PCT Filed Jun. 29, 1991 PCT Pub. No. WO92/01221 PCT Pub. Date Jan. 23, 1992.An ultrasonic test device for rotationally symmetrical test specimens permits performing oblique error testing. A probe carrier is mounted within a bore hole of a rotor such that its position can be rotationally adjusted about the axis of the bore hole and also adjusted longitudinally in the direction of the axis of the bore hole. Thus, especially in combination with an angle probe or an inclination-adjustable probe, the acoustic irradiation angle can be adjusted by rotation of the probe carrier. In this way, it is possible to achieve test paths for rotors that range continuously between every test spiral pitch.
