LTD., Wuhan University of Technology, Wuhan 430070,ChinaAbstract:automatic The aim of this paper was to establish the hardware frame of DC bridges verification, to program by Verification Regulation of the DC bridges, to analysis the data and to realize the automatic verification and print the report. This system used Fluke 5520A as a multi-functional signal generator which can output standard resistance to calibrate DC bridges. GPIB bus technology was applied between computer and Fluke 5520A. Software design was based on VB6.0. The program technology on GPIB program technique was introduced especially. The system changed the tradition manual operation, simplified the calibration process, enhanced the working efficiency and has avoided the human error.[著者文摘]
