An improved magnus measuring apparatus for providing an automatic initial setting at high speed in testing a plurality of biological specimens which moves elastically with beats, wherein a tensile force is applied on a specimen by moving the transducer connected thereto with use of a motor to be driven and stopped under the control of a control unit, and thereby the rotating speed of the motor is increased gradually at least for a predetermined period of time from the start and then kept at high speed for bringing a bottom value of the tensile force to enter an extent of preliminarily set initial value. In another aspect of the invention, a detected tensile force is sampled for detecting a peak of the tensile force and a threshold value is renewed in succession from the initial setting based on detected peak and bottom values, and then detecting a peak of the tensile force being caused from the beats of the specimen, hence said tensioning is so controlled as to adjust the detected bottom value to be in an extent of preset tensile force.
In a measuring apparatus for measuring physical parameters of a specimen being subjected to one or more substances, including a transducer unit for detecting a tensile force being applied on a specimen by pulling the specimen at one end thereof whilst the other end of which is fastened, tensioning means for applying a tensile force on the specimen by moving the transducer against the specimen in response to an amount of rotations of a motor, and a control unit for adjusting the tensile force to be applied on the specimen by controlling the tensioning means, said measuring apparatus comprising:
In a measuring apparatus for measuring physical parameters of a specimen being subjected to one or more substances, including a transducer unit for detecting a tensile force applied on a specimen, a control unit for measuring the tensile force based on a detected signal at the transducer unit, specimen holding means, for storing the specimen during testing, and fluid supply means for supplying a fluid to said specimen holding means,
