Abstract: A method to use the memory testing technology for the simultaneous record of the voltage curve of chemical battery and the geomagnetic signal in the trajectory is presented for the test requirement of activation time of small-caliber fuze chemical battery. The relative activation time of chemical battery and the testing principle are given. The generation method of mutation magnetic field and the distortion performance of local magnetic field are analyzed, and a dynamic recovery test method and the experimental data are given. The experimental results show that the proposed method can be use to get the voltage curve of chemical battery, the time when a projectile passes a muzzle, and the relative activation time of chemical battery, which has an important significance to optimize the cell performance and improve the precision of fuze.
