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. 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。
An analog oscilloscope automatic calibration system is designed and realized using Microsoft Visual C + + 6.0 programming environment on GPIB interface in this paper. 本文利用VC++6.0开发环境,设计并实现了一种基于GPIB接口的模拟示波器自动校准系统。
