For blood pressure measurements using the oscillometric method with Sensor-CASSY (5210.524013) or Pocket-CASSY (5210.524006, 5210.524018) without stethoscope and microphone. The pressure variations which are caused by the pulse waves are transmitted by the arm collar and measured together with the falling pressure in the arm collar. Alternative for use with the Mobile-CASSY (5210.524009A) after the auscultatoric method (designed by Korotkov). The characteristic noise phenomena are listened to with a stethoscope (additionally required). The universal biology measuring instrument (5210.531837) gives an audible sound for the pressure variations.
