Abstract
Perfeccionamientos en dispositivos de comprobación para indicar una tensión eléctrica y su polaridad, del tipo que comprenden dos empuñaduras dotadas de unas juntas de contacto y unidades mediante un cable, y contiene en una de estas empuñaduras elementos de indicación óptica, caracterizados porque están interconectadas por lo menos dos etapas de indicación que consta cada una de una interconexión de por lo menos una resistencia y un elemento indicador óptico con amplificadores separadores interconectados que trabajan en forma no lineal, y en acción conjunta diferencia la tensión aplicada según su valor que se halla en un campo de tensión seleccionado, y la indican en forma escalonada correspondientemente a los campos de tensión seleccionados.
