The difficult point of dynamic calibration technology is the dynamic calibration method for non-electricity transducers. It is reasonable with some premise that the results from the static calibration are used to the dynamic one. The dynamic calibration of thermo-transducer is facing more problems than the dynamic calibration of pressure transducers. The realization and understand of the metrology concept are promoted and developed by the research on dynamic calibration technology. The system analysis of the characteristics of the calibrated object is more important than the measurement based on trace-to-source and will become the first concerned items of metrology.
