Beschreibung
Zusammenfassung:	Method for the validation of a fuse head in an electronic detonator, wherein said detonator comprises: a reference resistor, a fuse head, at least one capacitor and switching means, wherein in a first position of the switching means, the reference resistor is connected to the at least one capacitor forming a first RC circuit, and in a second position of the switching means, the fuse head is connected to the at least one capacitor forming a second RC circuit; the method comprising the following steps: measuring at least once a first charge time; activating the switching means to the second position to replace the reference resistor in the RC circuit with the fuse head; measuring at least once a second charge time; and determining the deviation of the second charge time from the first charge time.
