虚拟测量仪器的校准方法

The calibration method of the virtual measurement instrument

基于计算机的虚拟测量仪器比盒式测量仪器的成本要低,近年来应用普及很快。它与传统的盒式测量仪器一样,具有一个校准有效期,因而需要进行定期校准以确保测量精度,本文介绍对基于计算机的测量仪器进行内部和外部校准的方法。

The cost of the computer virtual measurement instrument is less than the box shaped measurement instrument,so the speed of its popularization and application is very fast in the last fow years.It is the same with the traditional box shaped measurement isntrumetn,also has a calibration expiration data,so meed regular calibration to ensure the measurement precision,this paper introduces the inside and outdide and outside calibration method of the computer measruement instrument.
