Vincent de Franco 05.May.07	1 EM84 (EM84) Avec une tension de 250V et une charge de 470k ohm, 0 à -22V de tension sur la grille permet de faire varier la taille de la barre d'affichage de 0 à 21mm. Une caractéristique de gain variable permet en plus d'améliorer la sensibilité pour les signaux plus faibles.
