Le présent document spécifie les règles générales de réglage de l''échelle de la base de temps et de la sensibilité (ou commande gain) d''un détecteur de défaut ultrasonore à commande manuelle à visualisation de type A. L''objectif est de pouvoir effectuer des mesurages reproductibles de la localisation et de la hauteur d''écho du réflecteur. La technique en immersion et les techniques utilisant plus d''un traducteur ne sont pas couvertes par le présent document.
This document specifies the general rules for setting the time-base range and sensitivity (i.e. gain adjustment) of a manually operated ultrasonic instrument with A-scan display in order that reproducible determinations can be made of the location and echo height of a reflector. This document is applicable to contact techniques employing a single probe with either a single transducer or dual transducers. This document does not apply to the immersion technique and techniques employing more than one probe.
