The problems lead to that when the output power of the in-line detonator is tested in different occasions, the safety can not be effectively ensured, meanwhile, the testing efficiency is lower in the small-batch sampling process, the tool loss is large, the consistency of the testing conditions is poor, and the production and the application of the in-line detonator are restricted.
