Abstract： Aiming at overcoming the shortcomings of the traditional engineering test instrument and improving the controllability and the control precision of the testing，a new type of measurement and control instrument was developed. The instrument with single chip micycco（SCM） and converter as the main unit component was made up of the host computer and actuator which communicate via RS485.Control algorithm of the test system was a result summarized from a lot of experiments，and all electrical interferences in testing were also eliminated. The feedback of all sensors and the process were monitored in real time in order to realize continuous measurement and control. Compared with traditional instrument，this instrument has improved stability，manipulation，the control precision of the measurement and control tests increases at least 10 times. The results indicate that the application of the converter in the test instrument is very effective.
