数字仪表自动校准中通信程序的编程方法

数字多用表在企业、实验室中的应用越来越广泛，为了提高校准效率，我们利用可程控校准器和计算机以及具有通讯接口的数字多用表组成自动校准系统来对数字多用表进行校准。自动校准软件中通信部分程序是关键和难点，本文用实例详细说明了如何实现微机和被校仪表之间通信，并且列出了用VB语言编制的源代码。

The Method of Communication Program For Digital Multimeter's Automatic Calibration

The digital multimeters are widely used in factories and labs, to improve the efficiency of calibration , we use the programmable calibrator and the computer to make an automatic calibration system with the digital multimeters which have communication interface. In the automatic calibration program , the communication part is the key and difficult, the paper uses an actual example to explain how to achieve the communication between the computer and the calibrated digital multimeters, and lists the original codes in VB language.
