Abstract

Il dispositivo comprende una punta di contatto (2) ed una massa interna, situata nell'impugnatura (1a).Questa massa interna si trova collegata alla terra, sia attraverso l'impedenza di ritorno costituita dal collegamento attraverso l'operatore che tiene nella sua mano l'impugnatura (1a), sia attraverso un cordone di messa a terra (7), con una spina (8), che si può introdurre in una presa (6) collegata alla massa interna, ed una pinza a coccodrillo (9), affinché la sensibilità del dispositivo di controllo (1) sia la stessa con e senza cordone di messa a terra (7), la presa (6) e la spina (8) sono bipolari, le due boccole della spina (8) sono in corto circuito e sono collegate al cordone (7) e, fra gli spinotti della presa (6), si trova una resistenza di piede di una catena di resistenze fra la punta di contatto e la massa interna.
