Internet-based calibration of measurement instruments

In a conventional calibration service, clients send their instruments to a laboratory for routine calibration, during which the clients are not able to use their instruments due to downtime. Some of their instruments are huge and heavy such as power source transformer which is difficult to be transported. A solution to these problems is to send an engineer together with measurement instrument to a client site to perform the calibrations. Another way of solving the problem is to send only the measurement instrument to a client site where the instrument and the unit under test are controlled by a computer that links with the laboratory computer over the Internet. The calibration engineer can monitor the calibration progress remotely from his laboratory without going to the site. This can improve the calibration service and bring satisfaction to the clients. The research conducted here is to develop a calibration system that allows the client instruments to be calibrated at the remote location. The existing Internet facility and its advancement pave the way for development of Internet calibration system. The methodology of internet calibration is based on the technology of client-server applications. It is distinguished by the connected online calibration service that it provides. Customers from various industries and services will benefit from this implementation. Their instruments performances are directly traceable to national laboratory. Experts from national laboratory can share their skills and knowledge with the customers.
