CARACTERISTIQUES
ST-5-AS est un appareil de mesure précise de la valeur (R-L-C) des composants passifs, notamment pour montage en surface. Sous la forme de brucelles a la prise en main facile, les extrémités sont dorées pour un meilleur contact. En mode "AUTO", La sonde détecte automatiquement le type de composant et affiche sa valeur; un 2eme affichage indique les valeurs R, L ou C additionnelles (comme par exemple la résistance série d'une capacité). La fréquence du signal de test est programmable.
