Étalons
Le respect des normes dans tout secteur est essentiel pour vérifier périodiquement la précision des instruments. En comparant les mesures aux valeurs connues, les lectures de sortie détectent les erreurs et informent le personnel des ajustements nécessaires. Une fois les réglages des instruments manuels ou automatiques réinitialisés à zéro, les conditions rétablies garantissent des performances optimales. L’étalonnage avec des standards concentrés élimine la possibilité que des changements environnementaux provoquent des erreurs instrumentales lorsque la précision est primordiale.
