Abstract

Cette invention concerne un équipement d'essai électrique portatif comprenant: une sonde, une unité de contact de terre servant à venir au contact d'une borne de terre d'un objet mesuré; une unité d'entrée de tension permettant de recevoir une tension appliquée depuis la sonde; une unité de commande servant à appliquer une tension d'essai d'un niveau recommandé sur l'unité d'entrée de tension, et à émettre un signal de commande pour indiquer une terre lorsqu'un niveau de tension appliqué par l'unité d'entrée de tension est inférieur au niveau zéro, pour indiquer un état d'attente de mesure lorsque le niveau de tension est au niveau de la tension d'essai et pour indiquer un niveau de tension détecté lorsque le niveau de tension est supérieur à une tension de référence recommandée; et une unité d'affichage qui permet de donner une indication en fonction du signal de commande émis par l'unité de commande de façon que l'état d'attente de mesure puisse être facilement reconnu par un utilisateur et qui comprend une pluralité de lampes qui sont sélectivement éclairées pour que l'utilisateur puisse reconnaître intuitivement une tension mesurée.
