High-precision calibration ofCalibrating multi-parameter testing equipment plays an important role in improving the performance of inertial devices in practical conditions. By introducing latest developments of calibration standards for multi-parameter testing equipment, the shortcoming of isolated calibration thatwhich caused by the difference between the isolated calibration environment and the composite condition produced by the multi-parameter testing equipment is analyzed. To solve the problem and improve the capability of calibrating multi-parameter testing equipment, key points including smart transfer standard, synchronous measurement and dynamic calibration of multiple asynchronous variables, and designation of testing equipment are it is suggested to develop transmission standards suitable for multi-parameter composite environment, carry out research on synchronous acquisition and dynamic calibration technology of multi-channel asynchronous data, and carry out research on metrological design of multi-parameter test equipment to form a metrological technology system supporting multi-parameter test.
