Section 57.6407 - Circuit testing A blasting galvanometer or other instrument designed for testing blasting circuits shall be used to test the following:
(a) In surface operations- - (1) Continuity of each electric detonator in the blasthole prior to stemming and connection to the blasting line;
- (2) Resistance of individual series or the resistance of multiple balanced series to be connected in parallel prior to their connection to the blasting line;
- (3) Continuity of blasting lines prior to the connection of electric detonator series; and
- (4) Total blasting circuit resistance prior to connection to the power source.
(b) In underground operations- - (1) Continuity of each electric detonator series; and
