Design for the auto-verification equipment of electronic scale with LabView

A new auto-verification equipment of electronic scale was introduced.The LabVIEW was adopted as the software development platform of the equipment.The LabVIEW software communicates with the PLC through the OPC.So the standard weight was controlled.The camera reads the indication of the scale and the calibration was done.The equipment has a good prospect of application for its high measurement accuracy and short verification time.
