Development and Application of Semi-automatic Calibration System for Clamp Ammeter Based on Lab VIEW
In this paper,the semi-automatic calibration system of clamp ammeter is developed to solve the prob-lems of various kinds,different ranges and low calibration efficiency.The results show that by using LabVIEW to build a software platform,the system can not only automatically call the calibration point in the database,control the output signal of the calibration source,but also manually copy the reading of the ammeter,and automatically calculate the error to judge,realizing the semi-automatic calibration of the clamp ammeter.
