Internet-Enabled Calibration

Abstract

Calibration of measuring instruments provides the confidence in measurements. It is the obligation of every laboratory to have its measuring equipment calibrated in regular intervals. This obligation means that the laboratory must send its equipment to the calibration laboratory every year or two depending on the calibration intervals. During this time the equipment is not available and this presents a financial burden to the laboratory of the customer. Since many of the modern instruments include some communication interfaces, it was made possible to create an Internet-enabled calibration system. This term encompasses a wide range of possible applications and services. The Internet-enabled calibrations must address several problems not present in standard calibrations, including security issues, since the equipment is not always under direct control of the calibration laboratory personnel who will sign the calibration certificate. As the traceability and integrity of the calibration process directly depends on the measured data, the reliable and secure remote control and monitoring of instruments must be a crucial aspect of Internet-enabled calibration technologies.
