<p>A delay charge (3) is inserted into a small firing tube (1) closed at one of its ends, whereafter the filling height is measured. Only when the filling height (a) of the delay charge (3) is sufficient, an opening (4) is provided in the bottom (2) of the small firing tube (1), so that the charge of the detonator (5) of the grenade fuse can only be fired by the delay charge (3) if the height thereof is sufficient. </p> |
