ABSTRACT:
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.
