Abstract: A kind of automatic explosive tester used in aerosystem was designed. The main function, technical index, test principle and system composing of the tester was introduced. The resistance test and insulation test of the explosive device were carried out by the tester. The realtime test data was compared with the corresponding data in the eligible certificate, and the data was judged whether it is eligible or not. The last register was stored in the USB flash disc. The testtime registering function and failure informing function were provided in the tester. Through debugging and testing, the tester runs reliably and stably in a long time, and the user′s requirement was completely satisfied.
