Influencia de la automatización de ensayos de flujo luminoso total en el cálculo de incertidumbre combinada y en el tiempo de ejecución del ensayo. Figempa [online]. 2018, vol.5, n.1, pp.71-78.

The calculation of the combined uncertainty of luminous flux tests carried out in an integrating sphere is a very important value for the accreditation of INER’s Lighting Laboratory under the ISO/IEC 17025 standard. The values ​​of the measurement devices used within the test should be registered manually by the operator, for which an automatic data acquisition system was implemented by integrating the devices into an application developed in LabVIEW that includes a real-time analysis of the luminous flux stabilization of the lamp and the calculation of the uncertainty based on the model developed by INER’s Lighting Laboratory. The present work analyzes the influence of the automation of the process of acquisition, analysis and use of the data for the calculation of the uncertainty, comparing a designated test of a high discharge lamp using the manual system and the automated system for the calculation of the combined uncertainty of the luminous flux test within an integrating sphere.

Palabras clave : automation; integrating sphere; luminous flux; combined uncertainty.
