<p>PURPOSE: To achieve a highly reliable detection with less error by specifiedly controlling a heater and setting the temperature of a cuvette to a set value and feedback-controlling an electromechanical transducer, adjusting the vibration displacement of a probe, and determining viscoelasticity with a microcomputer. CONSTITUTION: An empty place for housing a cuvette A38 for housing the fluid sample of a head assembly A24 is heated by a heating transducer Q48, the temperature of the sample at that time is detected by a thermistor RT46, and the difference to a set balance temperature is outputted as an error signal. Then, the set signal is integrated and the transducer Q48 is controlled so that the set balance temperature and a detection temperature maintain an isotherm relationship by a signal indicating an integer part. Similarly, the vibration displacement of a probe is adjusted by an electromechanical transducer via a feedback loop formed by the supply output of the electromechanical transducer and stress output, viscoelasticity is automatically determined by a microcomputer, and a highly reliable fluid viscoelasticity inspection can be made with a small error.</p> |
